A study of multiple-input multiple-output radar

In this paper, the present MIMO radar concepts are summarized, and MIMO radar performance is analysed. Next an example of using spatial information to improve the resolution of SAR system is given, and it helps us to understand the spatial information correctly. Then the diversity technique in wireless communication and the MIMO radar technique are compared and analysed, and the pattern diversity is proposed to be used in MIMO radar. Moreover the comparability between the array pattern and the ambiguity function of the periodic signal is analysed, and some waveform design methods can be used in removing the angle ambiguity in array antenna.
