Research on Convolution Jamming Technique Based on Triangle Wave Modulation

The design and application of anti-jamming waveforms such as LFM signal,make the radars still have the good ability to detect and track under the circumstances about complex clutter and noises.In order to solve this problem and gain better jamming effect,the convolution jamming technique based on the triangle wave modulation is built up under the pulse and noise convolution jamming,and the generic convolution jamming model in the time domain is designed,then its characteristics and jamming effects are analyzed,and the advantages are explained by simulation at last.The results show that triangle wave convolution modulation can realize the double jamming effects of deception and masking under the change of parameters,and also has the unique advantage.
