Abstract: Various technologies described herein pertain to opportunistically employing passive multistatic radar processing in automotive radar systems. A radar system of an autonomous vehicle is controlled to operate in an active mode during a first time period as the autonomous vehicle travels along a route. A transmitter and receiver of the radar system are enabled in the active mode. The radar system is controlled to operate in a passive mode during a second time period as the autonomous vehicle travels along the route. The transmitter is disabled and receiver is enabled in the passive mode. While in the passive mode, the receiver of the radar system receives a reflected radar signal responsive to a radar signal transmitted by a differing radar system of a differing autonomous vehicle. An object is detected based on the reflected radar signal and transmission information pertaining to the differing radar system of the differing autonomous vehicle.

Abstract: Technologies are described herein that are configured to identity detections output by a frequency-modulated continuous-wave (FMCW) radar system that are caused by an interfering signal. The detections are detected as being caused by an interferer based upon numbers of detections assigned to bins in a velocity-direction histogram.
