A system and method for sensing precipitation conditions near a vehicle. The precipitation radar system is mounted on the vehicle and includes a transmitter, a receiver, and an electronic control unit. The method transmits radar signals from the transmitter; receives reflected radar signals at the receiver; determines response information from the reflected radar signals for a region of interest; and uses the response information to determine precipitation conditions for the region of interest. The region of interest is defined, at least in part, by a range and the response information includes phase data, amplitude data, or both phase and amplitude data based on the reflected radar signals. The method and system may then use the precipitation conditions to control other responsive vehicle actions, such as activating a windshield heater, a windshield defroster, a windshield wiper or a combination thereof.

System and method for detecting precipitation using radar

The present application generally relates to improve accuracy and sensitivity in a vehicular radar system through improved radar beamforming by initially detection of potential objects using a field of view image and image processing techniques. Specifically, a system and method are taught for performing object segmentation and/or contouring on an image corresponding to a radar field of view. The detected objects from the image are combined with the raw radar data to generate a beamformed radar data.

Apparatus and method for improved radar beamforming

The present application generally relates to a method and apparatus for application trailering in a motor vehicle. In particular, the system is operative to determine a trailer type and handling characteristic of a trailer in response to a micro-Doppler signature of the trailer.
