Abstract

In multi-input multi-output (MIMO) radar systems, the sparsity of targets in the target space can be exploited by compressive sensing (CS) techniques to achieve either the same localization performance as traditional methods but with significantly fewer measurements, or significantly improved performance with the same number of measurements. This paper proposes a power allocation scheme for widely separated CSbased MIMO radar. In particular, the allocation scheme minimizes the correlation between the target returns from different search cells, or equivalently, the correlation between the columns of the sensing matrix. The proposed power allocation scheme is shown to improve the detection performance as compared to a uniform power allocation approach.
