MIMO Radar: Joint Array And Waveform Optimization

In this paper, techniques for the optimization of multiple-input multiple-output (MIMO) radar waveform correlations and array geometries are investigated. The primary focus of this study is improved angle-estimation performance. This performance can be characterized by the Cramer-Rao angle- estimation bound and by the threshold point. The threshold point indicates the signal-to-noise ratio (SNR) at which the angle- estimation performance of an estimation statistic deviates from the Cramer-Rao bound performance. Approximation techniques for estimating the threshold are introduced. Examples of joint waveform and array geometry optimization are presented.
