In addition to the general requirements for radar waveforms such as good resolution, low sidelobes, etc. MIMO radar waveforms also should possess good orthogonality. In this paper we give a brief over- view of MIMO radar waveforms, which are classified into four categories: (1) time division multiple access (TDMA), (2) frequency division multiple access (FDMA), (3) Doppler division multiple access (DDMA), and (4) code division multiple access (CDMA). A special circulating MIMO waveform is also addressed. The properties, as well as applica- tion limitations of different waveforms, are analyzed and compared. Some simulations results are also presented to illustrate the respective performance of different waveforms. ABSTRACT Introduction De par son archite
