Planning with imperfect information : interceptor assignment
… the problem of assigning a scarce number of interceptors to a wave of incoming atmospheric re-entry vehicles (RV). In this single wave, there is time to assign interceptors to a wave of incoming RVs, gain information on the intercept status, and then if necessary, assign interceptors once …

Fast interceptor of a dynamic object
… of noisy measurements. The ground vehicle (interceptor) is required to intercept the dynamic object at a predicted (catch) location in a finite amount of time. This time restriction presents quite a challenge given the inherent limitation in the vehicle's steering and maneuverability. The …

The Application of Reinforcement Learning for Interceptor Guidance
… can be highly maneuverable. To counter this, new interceptors must be developed. This work explores using machine learning for the guidance of these interceptors through applied steering commands, with the intent to improve upon traditional guidance methods. Specifically, proximal policy …

Adjustable Energy Saving Device for Transom Stern Hulls
… characteristics of a transom mounted interceptor on the Oliver Hazard Perry class frigate (FFG-7), in order to assess the potential of propulsion power reduction in a wide range of speeds. This study is aimed to design a stern interceptor with optimal efficiency not only at top speed, …

Development of environmental water monitors based on hydrostatic and flourescence detection techniques
… the accumulation of oil within an oil/water interceptor. Pollution from oil spillages is a major contaminate of water systems and the control of this potentially hazardous material has legal obligations. This liquid, which naturally separates from water, accumulates within the interceptor …

A new first order solution to the relative motion problem with applications to intercept and rendezvous
… describing the relative motion between an interceptor vehicle and a target vehicle in a circular orbit, has been developed by means of a transformation of the variables which occur in the differential equations of relative motion. The results of this analysis are compared with other first …

Satellite constellation design for mid-course ballistic missile intercept
… leads to a new paradigm of coverage where interceptor "reachability" replaces line-of-sight coverage. Interceptors in this concept are limited in their time of flight and AV capabilities. Classical design approaches, based on ground coverage, are employed to provide a priori constellations …

Analysis of a target defense game
… maneuvering reentry vehicle (evader) and missile interceptor (pursuer) engagement is modeled in two dimensions, with constant velocity vehicles subject to bounded accelerations. Parameterized guidance laws are constructed for both players and a continuous, but finite-dimensional game is …

Sustainable development of an integrated solid waste and wastewater treatment.
… oil that removed 99.9% of TPH from Sureclean interceptor effluent; and the Sureclean Advanced Water Treatment System (SAWTS), an advanced oxidation process that was demonstrated to reduce the TPH of contaminated groundwater collected from an ex-gas work. The treated effluent could be …

A novel personal cooling system for use by soldiers in hot climates
… cooling system for use by soldiers beneath their Interceptor body armor. An alpha prototype was constructed and was used to generate promising, quantitative results. This first level data was combined with an analysis of the strengths and weaknesses of the design to lay down the framework for the …

Analysis of digital communication signals and extraction of parameters
… from the standpoint of the unintended receiver (interceptor). Typical digital communication signals considered include Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), Frequency Shift Keying (FSK), and On-Off Keying (00K). The analysis emphasizes the use of available signal …

Ballistic missile tracking using the interacting multiple model joint probabilistic data association filter
The success of interceptors used by the United States ballistic missile defense program is jeopardized by the use of hostile missile decoy deployment and evasive maneuvers. The ability to discriminate between legitimate threats and decoys is a crucial requirement for interceptor algorithms. The …

Space-Based Missile Defense: The Past, the Present, the Future
… possible. This thesis details how space-based interceptor technologies have advanced since 1992 despite the official U.S. unwillingness to advance its ballistic missile defense program. Additionally, this thesis analyzes the potential of the current, and still politically handicapped, U.S. …

Creating an Integrated Ballistic Missile Defense System for the Gulf Cooperation Council Countries
… for such a system, including BMD radars and interceptor systems, have already been sold to GCC nations and are currently operational. By integrating these systems and creating an overarching command structure, the BMD capabilities for all of the GCC would be strengthened. This integrated …

Missile autopilot design using Mu-Synthesis
… to defend against these more stressing threats, interceptor missiles require greater maneuverability, faster response time, and increased robustness to more severe environmental conditions. One of the most critical missile system elements is the flight control system, since its time constant is …
