Abstract EN
Cognitive radar is an intelligent radar system, and adaptive waveform design is one of the core problems in cognitive radar research.
In the previous studies, it is assumed that the prior information of the target is known, and the definition of target spectrum variance has not changed.
In this paper, we study on robust waveform design problem in multiple targets scene.
We hope that the upper and lower bounds of the uncertainty range of robustness are more close to the actual situation, and establish a finite time random target signal model based on mutual information (MI).
On the basis of the optimal transmitted waveform and robust waveform based on MI, we redefine the target spectrum variance as harmonic variance, and propose a novel robust waveform design method based on harmonic variance and MI.
We compare its performance with robust waveform based on original variance.
Simulation results show that, in the situation of multiple targets, compared to the original variance, the MI lifting rate of robust waveform based on harmonic variance relative to the optimal transmitted waveform in the uncertainty range has great improvement.
In certain circumstances, robust waveform based on harmonic variance and MI is more suitable for more targets.
