Range-doppler and anti-interference performance of Cognitive Radar detection waveform

Cognitive Radar could adjust its transmit waveform to get the best outperform in the alternative targets and environments with a close-loop feedback. It has been regarded as one of the tendency of radar. Optimization waveform design method is one of the critical technologies of radar cognition. This article analyses the range-doppler and anti-interference performance of a most common cognitive radar detection waveform. Firstly, the signal model and waveform solved process are reviewed, and the ambiguity function of the waveform is calculated and analyzed; secondly, the decrease of the output SNR of the cognitive radar caused by the white and colored interference are respectively derived; Finally, the MTLAB numerical simulation results are given.
