Abstract:
A radar system for a ground vehicle includes a MIMO system including a plurality of transmitters, a plurality of receivers, and a controller including an interpreter in communication with the plurality of transmitters and the plurality of receivers. The transmitters include a first transmitter and a plurality of second transmitters, and each of the transmitters includes a signal generator in communication with a transmitting antenna that is disposed to transmit a radar signal. Each of the radar signals is a linear-frequency-modulated continuous-wave (LFM-CW) radar signal including a chirp-start portion, and each of the receivers includes a receiving antenna that is disposed to receive reflected radar signals. The transmitters are controllable such that the chirp-start portions of the LFM-CW radar signals from the second transmitters have progressively increasing time delays as compared to the chirp-start portion of the LFM-CW radar signal from the first transmitter.
