The problem of robust waveform design for multiple-input, multiple-output radars equipped with widely-spaced antennas is addressed here. Robust design is needed as a number of parameters may be unknown, e.g., the target scattering covariance matrix (at both transmit and receive side). A min-max approach is adopted, and the code matrix is designed to minimize the worst-case cost under all possible target covariance matrices. Surprisingly, the same min-max solution applies to many commonly adopted performance measures. Examples illustrating the behavior of the min-max codes are provided for the mutual information.

Abstract

The problem of robust waveform design for multiple-input, multiple-output radars equipped with widely-spaced antennas is addressed here. Robust design is needed as a number of parameters may be unknown, e.g., the target scattering covariance matrix (at both transmit and receive side). A min-max approach is adopted, and the code matrix is designed to minimize the worst-case cost under all possible target covariance matrices. Surprisingly, the same min-max solution applies to many commonly adopted performance measures. Examples illustrating the behavior of the min-max codes are provided for the mutual information.
