Integrated design on digital channelized reconnaissance and jamming
Song Libing, Chen Xinnian, Bo Guo · 2011
With various interlacing signals, the electromagnetic environment of current battlefield becomes more and more dense and complex. It becomes more and more difficult to jam coherent radar especially with the ability of pulse compression. To achieve accurate and effective reconnaissance and jamming against coherent pulse compression radar, a method of integrated design based on digital channelized reconnaissance and jamming is proposed. In the system, the techniques of frequency domain sub-band processing, fractional fourier transform and convolution jamming are used in the design to increase its radar signal detection and denoising capabilities, while the jamming signals generated by a quickly matching method, which are coherent as much as possible, can realize effective jamming.
