选择合适的波形是实现多输入多输出(MIMO)雷达的关键任务。除了对雷达波形的一般要求，如高分辨率、低副瓣等，MIMO雷达波形还应具有良好的正交性。本文简要介绍了MIMO雷达波形，将其分为四类：(1)时分多址(TDMA)；(2)频分多址(FDMA)；(3)多普勒分多址(DDMA)；(4)码分多址(CDMA)。文中还介绍了一种特殊的循环MIMO波形，分析比较了不同波形的特点和应用局限性。文中还给出了一些仿真结果，以说明不同波形的性能。
Choosing a proper waveform is a critical task for the implementation of multiple-input multiple-output (MIMO) radars. 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 overview 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 application limitations of different waveforms are analyzed and compared. Some simulations results are also presented to illustrate the respective performance of different waveforms.
