Abstract

See full text

A method includes disposing a spherical radar reflector at a location exterior a vehicle equipped with the vehicular sensing system. The vehicular sensing system includes at least two radar sensors disposed at the vehicle and a controller that processes received radio frequency (RF) signals received by the plurality of receivers of each radar sensor of the at least two radar sensors. Calibration RF signals are transmitted by at least one transmitting antenna of a plurality of transmitters of a first radar sensor and a second radar sensor the at least two radar sensors, and reflected first calibration RF signals are received by the plurality of receivers of the first radar sensor and the second radar sensor. Based on a distance between the first radar sensor, the second radar sensor, and the spherical reflector, the vehicular sensing system determines an orientation of the first radar sensor and the second radar sensor.
