Abstract :
This paper proposes a novel distributed multiple-input and multiple-output (MIMO) phased radar with orthogonal frequency-division multiplexing (OFDM) waveform, i.e., OFDM-MIMO phased radar system, to improve the detection performance of high speed moving target with radar cross-section (RCS) fluctuation. The parallel incoherent processing of the spatial diversity multi-channel echoes data in a short time, can weaken the effect due to the target´s high speed motion and RCS fluctuation.
