High Resolution FDMA MIMO Radar

Understand

Traditional multiple input multiple output radars, which transmit orthogonal coded waveforms, suffer from range-azimuth resolution trade-off.

• In this work, 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.
