Enhanced multistatic radar resolution via STC

MIMO radar can improve on conventional target detection, parameter identification, and target classification performance via diversity of, among other things, its simultaneously-transmitted waveforms. However, the mutual interference among the waveforms may lead to considerable performance degradation suppressing clutter near targets. In this paper, we consider the use of space time coding (STC) to mitigate waveform cross-correlation effects in MIMO radar. First, it turns out that a joint waveform optimization problem can be decoupled into a set of individual waveform design problems. Second, a number of monostatic waveforms can be directly used in a MIMO radar system, which offers flexibility in waveform selection. Numerical results demonstrate the effectiveness of STC in MIMO radar for waveform decorrelation.
