A fast jamming waveform design method based on distributed precision jamming

Distributed precision jamming is a new electronic countermeasure technology, which uses several small signal transmitting carriers to jam the specific targets precisely by energy focusing. One of the typical applications is precision electronic warfare (PREW)., where the waveform design is also the point to guarantee the jamming effect. In this paper, a rapid coordinate descent (CD) algorithm is used to generate the constant modulus jamming waveform efficiently in the standard PREW scenario, and it directly optimizes the objective function by sequential iteration, so that the optimization objective approximates the ideal value continuously. Then, the jamming effect of the waveform generated by the algorithm is analyzed by numerical calculation and comparison. The experimental results show that the proposed algorithm can provide reasonable constant modulus jamming waveforms suitable for distributed accurate jamming in a short time.
