A Shared Waveform Design and Processing Method for Integrated Radar Detection and Coherent Jamming Signal

The shared waveform design for integrated radar detection and jamming signal is an important research component of modern multifunctional integrated Radio Frequency (RF) systems. The integrated signals designed by the established research are only capable of forming incoherent jamming, which has a great demand on power. This paper proposes a new waveform design method for integrated radar detection and coherent jamming signal based on Linear Frequency Modulation (LFM) signal, which can form advanced and delayed false target jamming to enemy. In order to reduce the jamming of enemy LFM signals, an integrated signal receiving and processing method was proposed based on prior information to identify and suppress enemy LFM signals. Theoretical analysis and simulation results show that the integrated signal designed in this paper can form multi-order false target jamming to the enemy, and the enemy LFM signal is well suppressed after receiving and processing, thus achieving good radar detection performance.
