Optimalwaveform design for MIMO radarwith low probability of interception

In this paper, we consider the waveform design problem of multiple input multiple output (MIMO) radar in the presence of an interceptor. By the joint considerations of high estimation accuracy and low probability of interception, we formulate the problem as maximizing the mutual information with a constraint on the Kullback-Liebler (KL) divergence. Then it is converted effectively to a convex optimization, which can be solved efficiently to give the optimal waveform. Simulation results show that there exits the optimal tradeoff between the estimation accuracy and the probability of interception.
