Abstract :
In this paper we analyze the problem of waveform design for target detection in the presence of clutter and noise environment. We use the target priori characteristics to design the transmitted waveform. The waveform is designed by mutual information criterion. Firstly, we present the signal model and information theoretic approach to design waveform. Secondly, we discuss the waveform design is the one that maximizing mutual information between the target priori characteristics and the radar received signal. The results of simulation evaluate the efficiency of the proposed method to compare with the chirp signal.
