Abstract

Traditional multiple-input multiple-output (MIMO) radars, which transmit orthogonal coded waveforms, suffer from range-azimuth resolution tradeoff. In this article, we adopt a frequency division multiple access (FDMA) approach that breaks this conflict. We combine narrow individual bandwidth for high azimuth resolution and large overall total bandwidth for high range resolution. We process all channels jointly to overcome the FDMA range resolution limitation to a single bandwidth, and address range-azimuth coupling using a random array configuration.
