摘要:相对于传统雷达而言，新型雷达大多采用匹配接受和相干处理等抗干扰技术，极大地增强了雷达的检测的能力，使与雷达信号不相关的干扰信号不能得到相应的处理增益，明显减弱了压制或者欺骗干扰的效果，对先进雷达的有源干扰技术的研究提出了严峻的考验。4824

Title Modeling and Simulation of radar active jamming
Abstract
Coherent processing and matched reception technologies have been widely used in modern new radar, and greatly enhance the ability of anti-jamming. These technologies obviously decrease the efficiency of electronic jamming which signal waveforms are mismatched to the victim radar’s transmitted waveform. These radar present significant challenges to the research on techniques of electronic countermeasures.
This paper has mainly researched techniques about the active jamming modeling and simulation.
Firstly, this paper has researched the active jamming system and the deception jamming system. Secondly, the frame of the radar jamming system has been builded in the paper. Moreover, It has set up five Mathematical models, such as RF noise jamming, noise modulation jamming, noise FM radio jamming, distance deception jamming and speed deception jamming. Last but not most, this paper has programmed a set of software of the radar jamming system by MATLAB . And it has also simulated the five jamming signals, such as RF noise jamming, noise modulation jamming , distance deception jamming and speed deception jamming.
