Abstract:
A MIMO radar system. The system includes a transmitter array, a receiver array, the antenna distances in one of the transmitter and receiver arrays being below the Nyquist limit for unambiguous angle measurements, but the antenna distances in the combination of the transmitter and receiver arrays being above this Nyquist limit. The system further includes a control and evaluation unit, which is designed to transmit via the transmitter array a sequence of transmit signals, which are subdivided into multiple measuring blocks, in each of multiple repeatedly implemented measuring cycles, a uniform multiplex scheme being applied within each measuring block and the multiplex schemes varying from measuring block to measuring block, carry out a Doppler estimation and an angle estimation based on the receiver array, carry out a Doppler correction of the received signals based on the Doppler estimations, demultiplex the Doppler-corrected signals, and refine the Doppler estimations and angle estimations.
