Book Description
The DoD has a long history of developing and testing electronic warfare (EW) systems dating back to World War II. Over this period each of the Services has established test facilities and internal test processes designed to test and evaluate a wide range of EW systems. While each Service's facilities and procedures are tailored to match unique Service requirements, the overall process for testing EW systems is similar across the Services. The DoD Electronic Warfare Test Process, using a combination of modeling and simulation with measurement facility, system integration laboratory, hardware in the loop, installed system, and open air range testing, is designed to make the most of existing T & E technologies and resources to provide a comprehensive evaluation of EW systems. The process is a building block approach designed to build upon the strengths and minimize the weaknesses of each of the available test resources. However even with this process, there are two interrelated areas of particular concern in EW effectiveness testing: problems associated with correlating and interpreting EW test results, and availability of appropriate resources at the right levels of fidelity to support required T & E activities. The Joint Advanced Distributed Simulation (JADS) Joint Test and Evaluation (JT & E) was chartered to evaluate the use of Advanced Distributed Simulation to enhance the EW Test Process and address the problems identified above. A key aspect of this effort is the development, using existing test facilities, of a linked test environment with which to conduct the JADS EW test. JADS, in conjunction with the DoD CROSSBOW Committee, conducted the Threat Simulator Linking Activities Study, to specify a joint test environment for electronic warfare testing, a subset of which will be implemented to support the JADS EW test.

Book Description
The JADS JT & E program is an OSD sponsored Joint-Service test designed to determine how well an emerging technology - Advanced Distributed Simulation (ADS) - can support DoD test and evaluation (T & E) activities. The two-phase ADS test using an Electronic Warfare (EW) system will investigate the present utility of ADS for T & E, identify the critical constraints, concerns, and methodologies when using ADS for T & E; and identify the requirements that must be introduced in ADS systems if they are to support a more complete T & E capability in the future. The emphasis of the JADS EW test is not on evaluating the EW system performance in use as a test vehicle; rather, the emphasis of the test is on the performance of the ADS components and their relative contribution to EW systems T & E. The term ADS (which includes Distributed Interactive Simulation as a subset) is intended to support a mixture of live, virtual, and constructive entities. The ADS-oriented test approach will investigate numerous issues from the T & E perspective including distributed test control and analysis, network performance, relationships between data latencies, ADS induced data anomalies, use of the High Level Architecture (HLA), and Run Time Infrastructure (RTI). Time, cost, and complexity, as well as validity and credibility of the data are part of the evaluation. A series of tests have been designed which will support comparison of data and results obtained from open air range EW testing with two ADS-based tests. This paper focuses on the two ADS-based tests to evaluate the utility of Advanced Distributed Simulation (ADS) to support an Electronic Warfare system test. The paper describes the test objectives, scope, and test design process for creating a unique virtual EW test environment of linked components. Details describing the test methodology, the ADS test architecture for testing an EW system, and use of DMS0's High Level Architecture are provided.

Book Description
The End-To-End (ETE) Test, conducted under the auspices of the Department of Defense Joint Advanced Distributed Simulation (JADS) Joint Test and Evaluation (JT & E), is currently developing a synthetic test environment that can be used for future operational testing and doctrinal development. This synthetic test environment is a joint venture, involving both the ETE and the US Army's Test and Experimentation Command (TEXCOM), and will be used initially to conduct operational testing of the Joint Surveillance Target Attack Radar System (Joint STARS) and future C4ISR systems. The test environment will be the result of the merging of two advanced distributed simulation (ADS) environments that consist of live elements, hardware in the loop, DIS compliant simulations, and constructive legacy models. The ADS environments involved are the ETE Joint STARS Target Attack Environment and the Simulation Test Operational, Rehearsal Model (STORM) Environment. The plug and play aspects of this Joint Test Environment are best illustrated by current discussions with the US Air Force regarding the addition of an Air Force Target Exploitation Environment. Addition of this environment would allow the investigation of doctrinal issues of interest to both the Air Force and the Army, and further operational testing of Joint STARS. Additionally, the elements comprising the nodes may be represented by simulations or by the actual system, since all of the communication is doctrinally correct and may be passed using actual communications systems. As an example, the Improved Army Tactical Missile System could replace the currently simulated Army Tactical Missile System and operational testing could be rehearsed and conducted using a variety of operational and doctrinal schema. This paper describes the architecture of the Joint Test Environment, current developmental efforts, and potential future expansions and uses of the environment.

Book Description
The Joint Advanced Distributed Simulation (JADS) Joint Test and Evaluation (JT & E) was chartered by the Deputy Director, Test, Systems Engineering and Evaluation (Test and Evaluation), Office of the Secretary of Defense (Acquisition and Technology) in October 1994 to investigate the utility of advanced distributed simulation (ADS) technologies for support of developmental test and evaluation (DT & E) and operational test and evaluation (OT & E). The JADS Joint Test Force (JTF) is Air Force led with Army and Navy participation. The JADS JT & E program is scheduled to end in March 2000. The JADS JTF investigated ADS applications in three slices of the test and evaluation (T & E) spectrum: ADS support of air-to-air missile testing; ADS support for command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) testing; and the Electronic Warfare (EW) Test which explored ADS support for EW testing. The tasking to conduct an ADS-based EW test called for an airborne self-protection jammer (SPJ) as the system under test (SUT). The emphasis of the EW Test was on the performance of the ADS components and their contribution or impact to testing rather than on the performance of the SPJ pod itself. Measures of performance (MOPs) for the SPJ were identified as measures that would most likely be affected by distributed testing. Statistical comparison of the MOPs became the methodology for evaluating ADS. JADS evaluated distributed test control and analysis, network performance, relationships between data latencies, and ADS-induced data anomalies. Time, cost, and complexity, as well as validity and credibility of the data, were part of the evaluation.

The first phase provided a baseline of jammer performance data in a non-ADS environment that was then compared to the data collected in the second and third phases using an ADS environment. The second phase used a digital system model of the SPJ representing an early developmental test. The third phase used the SPJ mounted on the aircraft that was suspended in an installed systems test facility. This test represented a combined integration and effectiveness test that would occur late in the SPJ development.

Book Description
The Joint Advanced Distributed Simulation Joint Test and Evaluation (JADS JT&E) was chartered by the Deputy Director, Test, Systems Engineering, and Evaluation (Test and Evaluation), Office of the Secretary of Defense (Acquisition and Technology) in October 1994 to investigate the utility of advanced distributed simulation (ADS) technologies for support of development test and evaluation (DT&E) and operational test and evaluation (OT&E). The Electronic Warfare (EW) Test evaluated the utility of ADS to support EW systems testing. The EW Test was built on four discreet efforts intended to provide insight into the limitations of technology supporting ADS, the fundamental requirements that ADS architectures must support for EW T&E, and the application of ADS to EW testing. These efforts were 1) JADS-sponsored and managed self-protection jammer test, 2) OSD CROSSBOW Committee-sponsored Threat Simulator Linking Activity, 3) Defense Modeling and Simulation Organization (DMSO)-sponsored High Level Architecture (HLA) Engineering Protofederation (EPF), and 4) Army-sponsored Advanced Distributed Electronic Warfare System (ADEWS) development program. Each effort is described and results are discussed in this report.

Book Description
The Electronic Warfare During Close Air Support (EW/CAS) Joint Test was a two-phased multiyear joint service test designed to determine the effects of hostile air defense and electronic warfare environments on Army attack helicopter operations in concert with close air support operations. The objectives of Phase II were to evaluate the relative effectiveness of various mixes of Blue EW equipment on Red air defense and evaluate the effects of denying critical elements of the Red air defense capabilities in close air support and attack helicopter operations. This report provides an Army-oriented plan for appraising the EW/CAS Phase II test. The evaluation plan identifies specific questions of Army interest and provides a framework for the evaluation test data. The issues identified for evaluation include communications jamming, training, JAAT tactics, and the synergistic effects of Air Force EW equipment with an overall objective of assessing the Army's preparedness and ability to conduct attack helicopter operations in a desert mountain terrain against threat forces equipped with EW and air defense assets.

Book Description
The Joint Advanced Distributed Simulation (JADS) Joint Test Force was chartered by Office of the Secretary of Defense to investigate the utility of advanced distributed simulation (ADS) technology to test and evaluation (T & E). JADS executed three test programs (command, control, communications, computers, intelligence, surveillance and reconnaissance; precision guided munitions; and electronic warfare EW) representing slices of the overall T & E spectrum as well as observing other activity within the T & E community to form its conclusions. One of the slices, the Electronic Warfare Test, used the high level architecture in the creation of a synthetic environment to recreate a series of open air range flight test events. This paper discusses the JADS EW Test results with particular emphasis on the performance of the synthetic environment, the impacts of ADS on the EW Test results, and the lessons learned.

Book Description
The Joint Advanced Distributed Simulation (JADS) Joint Test and Evaluation was chartered by the Office of the Under Secretary of Defense (Acquisition and Technology) in October 1994 to investigate the utility of advanced distributed simulation (ADS) technologies for support of developmental test and evaluation (DT&E) and operational test and evaluation (OT&E). The program is Air Force led with Army and Navy participation. The program is currently scheduled to end in March 2000. The JADS Joint Test Force is directly investigating ADS applications in three slices of the test and evaluation (T&E) spectrum: the System Integration Test (SIT) explored ADS support of air-to-air missile testing; the End-to-End (ETE) Test investigated ADS support for command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) testing; and the Electronic Warfare (EW) Test explored ADS support for EW testing. Phase 4 of the ETE Test is the subject of this report. The ETE Test was designed to evaluate the utility of ADS to support testing of C4ISR systems. The test focused on the Joint Surveillance Target Attack Radar System (Joint STARS) as one component of a representative C4ISR system. The ETE Test also evaluated the capability of the JADS Test Control and Analysis Center (TCAC) to control a distributed test of this type and remotely monitor and analyze test results. The ETE Test consisted of four phases. Phase 1 developed or modified the components needed to develop the ADS test environment. Phase 2 used the ADS test environment to evaluate the utility of ADS to support DT&E and early OT&E of a C4ISR system in a laboratory environment. Phase 3 transitioned portions of the architecture to the E-8C aircraft, ensured that the components functioned properly, and checked that the synthetic environment interacted properly with the aircraft and actual light ground station module (LGSM).
