Robust waveform design for multi-target detection in cognitive MIMO radar

This paper considers the robust waveform design for improving performance of multi-target detection in cognitive multiple-input multiple-output radar. The goal of our robust waveform design is to maximize the worst-case detection probability of multiple targets based on the prior informations obtained from previous observations, under constraint of transmitted waveform energy. For accomplishing the goal, a two-step process is proposed. First, covariance matrix of probing signals is designed. Then, waveform is synthesized from achieved covariance matrix. The effectiveness of our proposed method is illustrated through numerical examples.
