Multi-Input Multi-Output (MIMO) Radar - Diversity Means Superiority

Abstract

A multiple-input multiple-output (MIMO) radar uses multiple antennas to simultaneously transmit several linearly independent waveforms. It also uses multiple antennas to receive the reflected signals. It has been shown that by exploiting this waveform diversity, MIMO radar can overcome performance degradations caused by radar cross section (RCS) fluctuations, achieve flexible spatial transmit beampattern designs, provide high-resolution spatial spectral estimates, and significantly improve the parameter identifiability. The MIMO radar can be grouped into two classes according to their antenna configurations. One class is the conventional radar array, in which both the transmitting and receiving antennas are closely spaced for coherent transmission and detection. The other class is the diverse antenna configuration, where the antennas are separated far away from each other to achieve spatial diversity gain.
