Book Description
Aviators rely heavily on Forward Looking Infrared (FLIR) imagery. Weather impacted terrain and targets significantly impedes an aircrew's ability to navigate and to rapidly and accurately detect and identify targets. Weather degradation increases target acquisition and identification times, subjecting the aircraft and crew to increased exposure to enemy threats and counterattacks, ultimately decreasing system lethality and survivability. The U.S. Army Engineer Research and Development Center (ERDC), the Air Force Research Agency (AFRA) and the U.S. Army Aviation Test Directorate, Operational Test Command tested the utility of the Infrared Target-scene Simulation Software (IRTSS) System as a mission planning and rehearsal tool for AH-64 Apache attack aviation. IRTSS translates information dominance into readily assimilated situational awareness by fusing tactical intelligence with weather intelligence. Increased situational awareness mitigates risk. and improves aircrew/aircraft lethality and survivability. The IRTSS software running in a commercial web browser generated FLIR scenes for the AH- 64 Target Acquisition Detection Site (TAD S) providing a mechanism for systematically accounting for weather and weather-related effects on the terrain. This technology optimizes for both the anticipated tactical situation and environmental conditions. Using control and test groups of Army aviators, we tested the improvements IRTSS brings to ranking Battle Position (BP) in comparison to using hard copy maps and the Aviation Mission Planning System (AMPS). The tests also measured the change in target detection times using live TADS video following previews of IRTSS scenes.

Book Description
Aviators rely heavily on Forward Looking InfraRed (FLIR) imagery to navigate and to rapidly and accurately detect and identify targets. Weather and weather impacted terrain and targets can significantly alter terrain-target infrared contrast relationships impeding an aircrew's ability to effectively use FLIR imagery for mission accomplishment, potentially increasing aviator's exposure to enemy threats and counterattacks, and ultimately decreasing system lethality and survivability. Pre-flight physics-based "through the sensor" infrared synthetic scenes can mitigate the impact of weather by portraying the weather impacted terrain-target infrared battlefield scenes accurately. The U.S. Army Engineer Research and Development Center (ERDC), the Air Force Research Agency (AFRA), and the U.S. Army Aviation Test Directorate tested the utility of the Infrared Target-scene Simulation Software (IRTSS) system as a mission planning and rehearsal tool for Apache attack aviation. Pre-flight infrared synthetic scene mission enhancement was quantified based on Battle Position (BP) rankings, as compared to the rankings of a Standardization Instructor Pilot (SIP), target detection times, number of target false detects, and number of target non- detects. Questionnaires were used to qualitatively assess the 'value' of pre-flight synthetic infrared scenes as judged by Army aviators.

Book Description
"Early fixed wing research demonstrated that potential cost and training benefits could be derived from simulation-augmented primary flight training. Unfortunately, more recent research in this area has been the exception, not the rule. This is especially true in the case of rotary wing (helicopter) aircrew training research. The present report reviewed the research literature on military aviation transfer of training (TOT) research, and examined the current U.S. Army Initial Entry Rotary Wing (IERW) Program of Instruction. An in-depth review was also conducted on the recent IERW simulation research performed by the Army Research Institute (ARI) Rotary Wing Aviation Research Unit (RWARU). Review of the IERW TOT research showed that a combination of synthetic flight simulation and criterion-based training had the potential for saving training time and costs in the aircraft. Adaptive training aids such as the ARI RWARU Intelligent Flight Trainer, also showed promise. A research program, focusing on revising the current IERW program to optimize the use of simulation, was proposed. This program would include (a) criterion-based instructional strategies, (b) low cost simulation, and (c) investigation of different combinations of simulator vs. aircraft training events, in order to determine the optimal simulator/aircraft training mix."--DTIC.

Book Description
This paper describes the recent addition, characterization, and integration of emerging technologies for dynamic infrared scene projection at the US Army Aviation and Missile Command's (AMCOM) Advanced Simulation Center (ASC). Infrared scene projection performs a vital role in the daily testing of tactical and theatre missile systems within these Hardware-in-the-Loop (HWIL) laboratories. Topics covered within this paper include the addition and characterization of new Honeywell and Santa Barbara Infrared emitter arrays, the integration and operation of the Honeywell and SBIR emitter array systems into a HWIL test, the development of high speed reduced-size IRSP drive electronics, the development of a NUC/characterization station, added software support, and the status of DMD-based infrared scene projector. Example imagery and test results from several of the projector systems are included within this paper.

Book Description
The U.S. Air Force Electronic Warfare Evaluation Simulator (AFEWES) is a government-owned, contractor-operated electronic warfare test facility located at Air Force Plant 4, in Fort Worth, Texas. The AFEWES is a Test and Evaluation (T & E) resource of the Air Force Flight Test Center (AFFTC), 412 Electronic Warfare Group (EWG), Edwards Air Force Base, California. AFEWES' mission is to perform effectiveness testing of Department of Defense (DoD) and allied electronic countermeasure techniques to enhance aircraft and aircrew survivability in combat. This paper describes the multi-service and contractor team that successfully defined, designed, developed, tested and implemented state of the art infrared PC based scene generator to be used by DoD. The paper also highlights: Team requirements and low cost solution, Leveraging government owned assets and developing partnerships across DoD.
