Adaptive waveform optimization method for OFDM radar communication jamming

摘要

In order to solve the problems of low utilization of transmit power and low efficiency of OFDM radar communication jamming shared signal waveform, an adaptive shared waveform optimization method is proposed. Firstly, the suppression interference entropy model, signal-to-noise ratio (SNR) and data information rate (SIR) models of shared signals are derived. Then, an adaptive OFDM shared signal waveform optimization model is established with the maximum entropy, signal-to-noise ratio and data information rate as the optimization criteria. Then, the KKT condition of the adaptive waveform is derived, and the optimal adaptive waveform is obtained by convex optimization toolkit Power distribution scheme. The results show that the designed waveform has the best jamming performance of radar communication.
