Book Description
Boost phase interception of ballistic missiles is envisioned as the primary response of the layered defense architecture implemented in the ballistic missile defense system. A limited time frame in which to take action and the necessity to implement hit-to-kill technology in the kill vehicle counterbalances the many advantages of boost phase interception. Direct hit missile technology is constrained by the requirement to minimize miss distance to a negligible amount between the kill vehicle and optimum aim point on the target. This thesis examines kill vehicle effectiveness, which is tantamount to miss distance, as a function of both the kill vehicle maximum acceleration capability and the guidance system time constant necessary to destroy a target. The kill vehicle guidance system is modeled in MATLAB as a fifth-order binomial series with proportional navigation. The simulation examines the effect of an accelerating target attributed to powered flight and aim point displacement caused by a shift in tracking point from the target plume to the payload when resolution occurs. The kill vehicle minimum requirements as indicated by the simulation include a lateral acceleration capability of four times the target acceleration and a guidance system time constant that is less than one-tenth the estimated flight time. (4 tables, 22 figures, 19 refs.)

Book Description
In recent conflicts, ballistic missiles have been used to achieve military and psychological objectives. With the proliferation of weapons of mass destruction (WMD), the threat of ballistic missiles as delivery platform for WMD is of concern. Defense against such threats becomes important. There are different guidance laws, like pursuit and proportional navigation (PN), for the missile interception of aerial targets. A new guidance algorithm was developed by John A. Lukacs and Prof Yakimenko in 2006 to demonstrate the feasibility of intercepting a ballistic missile during the boost phase. This trajectory-shaping guidance algorithm uses the direct method of calculus of variations that maximizes the kinetic energy transfer from the interceptor to the target. A study was conducted by applying this guidance law and examining the trade-off between the various critical parameters, like intercept geometry, time, altitude and trajectory, in the optimized solution. It provides insights into the feasibility and limitations of this guidance. A literature review of the drag model and comparison with the compensated PN guidance was also conducted. A new induced drag model was developed for future studies. The results verified that the trajectory-shaping guidance is feasible for the interception of ballistic missiles in the boost phase for a wide range of interceptor launch locations with respect to a ballistic missile detection point.

Book Description
A near-optimal guidance law has been developed using the direct method of calculus of variations that maximizes the kinetic energy transfer from a surface-launched missile upon interception to a ballistic missile target during the boost phase of flight. Mathematical models of a North Korean Taep'o-dong II (TD-2) medium-range ballistic missile and a Raytheon Standard Missile 6 (SM-6) interceptor are used to demonstrate the guidance law2s performance. This law will utilize the SM-62s onboard computer and active radar sensors to independently predict an intercept point, solve the two-point boundary value problem, and determine a near-optimal flight path to that point. Determining a truly optimal flight path would require significant computing power and time, while a near-optimal flight path can be calculated onboard the interceptor and updated in real time without significant changes to the interceptor2s hardware. That near-optimal guidance path is then converted into a set of command functions and fed back into the control computer of the interceptor. By modifying the second and third derivatives of the two-point boundary value problem, the intercept conditions can be varied to study their effects upon the optimal flight path regarding the maximization of kinetic energy upon impact.

Book Description
2019 Missile Defense Review - January 2019 According to a senior administration official, a number of new technologies are highlighted in the report. The review looks at "the comprehensive environment the United States faces, and our allies and partners face. It does posture forces to be prepared for capabilities that currently exist and that we anticipate in the future." The report calls for major investments from both new technologies and existing systems. This is a very important and insightful report because many of the cost assessments for these technologies in the past, which concluded they were too expensive, are no longer applicable. Why buy a book you can download for free? We print this book so you don't have to. First you gotta find a good clean (legible) copy and make sure it's the latest version (not always easy). Some documents found on the web are missing some pages or the image quality is so poor, they are difficult to read. We look over each document carefully and replace poor quality images by going back to the original source document. We proof each document to make sure it's all there - including all changes. If you find a good copy, you could print it using a network printer you share with 100 other people (typically its either out of paper or toner). If it's just a 10-page document, no problem, but if it's 250-pages, you will need to punch 3 holes in all those pages and put it in a 3-ring binder. Takes at least an hour. It's much more cost-effective to just order the latest version from Amazon.com This book includes original commentary which is copyright material. Note that government documents are in the public domain. We print these large documents as a service so you don't have to. The books are compact, tightly-bound, full-size (8 1/2 by 11 inches), with large text and glossy covers. 4th Watch Publishing Co. is a HUBZONE SDVOSB. https: //usgovpub.com

Book Description
This paper details the simulation process followed to design a model of the Kinetic Kill Vehicle portion of a Ballistic Missile Defense simulation. In order to have full knowledge of the system specifications, we went through the design process to find vehicle's propulsion characteristics, center of gravity, and moments of inertia. Using the simulation modeling goals as a guide, the system was then abstracted into a set of desired behaviors. These include ballistic motion, rotational motion, propulsion, vehicle control, communication with the ground, and operation of an on-board sensor. Finally, the paper briefly defines the governing equations used to implement the model in the simulation. Overall, when the presented approach was followed, the simulation process provided a clear progression between steps and a robust method for system modeling.

Book Description
The objective of this thesis is to investigate the requirements and limitations of boost phase ballistic missile intercept systems that contain interceptor and its guidance sensors (both radar and infrared). A three- dimensional computer model is developed for a multi-stage target with a boost phase acceleration profile that depends on total mass, propellant mass and the specific impulse in the gravity field. The radar cross-section and infrared radiation of the target structure are estimated as a function of the flight profile. The interceptor is a multi-stage missile that uses fused target location data provided by two ground-based radar sensors and two low earth orbit infrared sensors. Interceptor requirements and limitations are derived as a function of its initial position from the target launch point and the launch delay. Sensor requirements are also examined as a function of the signal-to- noise ration during the target flight. Electronic attack considerations within the boost phase are also addressed including the use of decoys and noise jamming techniques. The significance of this investigation is that the system components within a complex boost phase intercept scenario can be quantified and requirement for the sensors can be numerically derived.
