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.
