Waveform Design of Cognitive Radar Based on Maximum SINR and MI
2020
In real battlefield, the prior information of radar target is not easy to obtain. The waveform based on the prior information of radar target can not meet the needs of detection and parameter estimation. This paper considers the optimal waveform design method under different task energy constraints. In order to improve the detection performance of radar system, the signal-to-interference-to-noise ratio (SINR) of known and random extended targets can be maximized; in order to improve the performance of parameter estimation, the mutual information (MI) between radar echo and spectrum response of random targets can be maximized, and the optimal waveform design and simulation are carried out.
