Optimal radar waveform for parameter estimation and electromagnetic compatibility

Abstract

The problem of bi-objective radar waveform design for target estimation and electromagnetic compatibility is addressed in this paper. To improve the estimation performance, the mutual information (MI) between the received signal and the target impulse response is used as the objective function. While for electromagnetic compatibility, the spectral power of the transmitted waveform should be suppressed in some certain frequency bands. The optimal radar waveform is designed for both the aforementioned two objective functions under the energy and modulus constraints. An iterative algorithm is proposed to solve the bi-objective optimization problem. Optimal waveform is obtained for different weights of the two objective functions. The performance of the waveform is evaluated in terms of MI and spectral power allocation in the frequency bands.
