This document describes techniques and systems to detect and localize NLOS objects using multipath radar reflections and map data. In some examples, a processor of radar system can identify a detection of an object using reflected EM energy and determine, using map data, whether a direct-path reflection associated with the detection is within a roadway. In response to determining that the direct-path reflection is not located within the roadway, the processor can determine whether a multipath reflection (e.g., a multipath range and multipath angle) associated with the detection is viable. In response to determining that the multipath reflection is viable, the processor can determine that the detection corresponds to an NLOS object. The processor can also provide the NLOS object as an input to an autonomous or semi-autonomous driving system of the vehicle, thereby improving the safety of such systems.

Detection and localization of non-line-of-sight objects using multipath radar reflections and map data

An illustrative example object detection system includes a plurality of first transmitters that respectively transmit a first signal at a first time, a plurality of second transmitters that respectively transmit a second signal at a second time, a plurality of receivers that receive the signals, and a processor that is configured to determine whether a transmission timing phase shift exists between the received first signals and the received second signals based on a relationship between matrices including the received signals.
