摘要:
A MIMO radar system. The system includes transmitter and receiver arrays, and a control and evaluation unit, designed to: transmit transmission signals according to a time and frequency multiplex scheme in each of multiple repeatedly implemented measuring cycles, the time space and frequency space being divided into non-overlapping time slots and frequency sub-bands and only one single transmitting antenna being active in each time slot and transmitting in only one single frequency sub-band, carry out preliminary distance estimations and Doppler estimations, each based on signals of an individual transmitting antenna, in a first evaluation stage based on signals received in one measuring cycle, and carry out joint distance, Doppler, and angle estimations using a multi-dimensional estimation algorithm in a second evaluation stage based on phases of the signals transmitted by various transmitting antennas, results of the first evaluation stage being refined by increasing the accuracy and/or by eliminating ambiguities.
