Abstract :
For shedding light on the properties of range-folding, Doppler-frequency aliasing, and clutter rejection in match filtering of the MIMO radar, which are not available in publications, the paper focuses on analyzing and optimizing the ambiguity properties of the MIMO radar including the unambiguous delay interval and Doppler interval, the unambiguous area and the sidelobe level in the unambiguous area. As a result, the unambiguous area of the MIMO radar in the delay-Doppler plane is optimized to be 1 (dimensionless), and the sidelobe level in the unambiguous area is optimized to equal the sidelobe level of the SIMO radar, thus the MIMO radar can match the SIMO radar in the performance of range-folding, Doppler-frequency aliasing, and clutter rejection in match filtering.
