Simulation And Evaluation Of Radar Deception Jamming Effect On Ballistic Missile Defense Phased-array Radar

Radar jamming is a very important content of nowadays electronic warfare. More and more countries make great efforts to develop techniques of theater ballistic missile (TBM) and theater ballistic missile defense (TBMD). Under this international strategic background, it is of great military value to study advanced radar jamming techniques and evaluation of radar jamming effect.This thesis consists of four sections. In section one, the phased-array radar system of ballistic missile defense is divided into five blocks. And then, mathematical model is established after analyzing each functional module of phased-array radar system.In section two, based on simulating the phased-array radar and analyzing the ballistic characters of TBM, the characters of phased-array radar TBMD and divide means of search region is discussed. Meanwhile, much emphasis is placed on the differences of radar's search region when preliminary detect probability changes, and the optimum search strategy is presented.In the third section, based on the phased-array radar mathematical models established in section one, mathematical models of range pull-off jamming is presented. Combining simulation, we investigate radar jamming effect of range pull-off jamming on phased-array radar, especially under condition of maneuvering target and non-maneuvering target. Some conclusions are obtained, which are valuable to optimize penetration. And then, evaluation rule and measurement of radar range pull-off jamming effect are presented .Multiple-target deception jamming is modeled mathematically in section four. And, the effect of multiple-target deception jamming is discussed when the distance between targets changes, with more emphasis on issues in radar data processing caused by multiple-target deception jamming and the advantages of adaptive tracking data rate in dynamic electromagnetic environments. Lastly, evaluation rule and measurement of radar multiple-target deception jamming effects are investigated briefly.
