Abstract :
MIMO (multiple-input and multiple-output) radar with OFDM (orthogonal frequency-division multiplexing) waveform, i.e., OFDM-MIMO radar, transmits diverse carrier frequency narrowband signals, which can be synthetized to a wideband one to improve the resolution via a method in this paper. We firstly establish the echo model of OFDM-MIMO radar, and then derive the expression of phase compensating factor in time-domain. Simulations demonstrate the feasibility.
