Abstract:
1. A sensor module configured to be located behind a window of a vehicle to detect an object through the window and in an area about the vehicle, said module comprising: an antenna configured to emit a radar signal through the window and into the area, wherein the radar signal is characterized by a transmitted polarization of the radar signal, wherein the transmitted polarization is influenced by a first transmit signal received at a first port of the antenna and a second transmit signal received at a second port of the antenna; and a controller configured to output the first transmit signal and the second transmit signal, wherein the first transmit signal is characterized by a first characteristic, and the second transmit signal is characterized by a second characteristic, wherein a relative difference between the first characteristic and the second characteristic is selected based on a preferred angle of propagation of the radar signal through the window.
