Power Allocation Strategies for MIMO Radar Waveform Design

The role of waveform design is central to effective radar resource managementfor state-of-the art radar systems. The waveform shape employed by any radar system hasalways been a key factor in determining the performance and application. The design ofradar waveform to minimize mean square error (MMSE) in estimating the target impulseresponse is based on power allocation using waterfilling. This paper shows the effect ofvarious power control strategies in the MMSE performance of the waveform design. Wefind that the truncated power control strategy exhibits a good MMSE performance. Theperformance improvement results from the fact that with the truncated power control nopower is wasted in poor quality modes.
