Claim:
1. A method for controlling a radar system of a vehicle, the radar system having a plurality of transmitters and a plurality of receivers, the method comprising the steps of: transmitting, via the plurality of transmitters, a first plurality of radar signals from the vehicle; receiving, via the plurality of receivers, a second plurality of radar signals pertaining to an object that is in proximity to a roadway on which the vehicle is travelling, the second plurality of radar signals directed from the object after the first plurality of radar signals contact the object; determining, via a processor, a location of the object with respect to the vehicle based on the second plurality of radar signals; determining, via the processor, an azimuth angle for the object with respect to the vehicle based on the second plurality of radar signals; determining, via the processor, an elevation angle for the object with respect to the vehicle based on the second plurality of radar signals; determining, via the processor, a range for the object with respect to the vehicle based on the second plurality of radar signals; generating, via the processor, a plurality of feature vectors based on the second plurality of radar signals, the location, the azimuth angle, the elevation angle, and the range; generating, via the processor, a three dimensional representation of the object using the plurality of feature vectors via association of the second plurality of radar signals to a three dimensional array, the three dimensional representation comprising a union of the plurality of feature vectors over the three dimensional array, wherein the three dimensional array is constructed such that the three dimensional array has a first dimension based on the azimuth angle, a second dimension based on the elevation angle, a third dimension based on the range, and a center that is based on the location of the object; extracting features from the second plurality of radar signals using the three dimensional representation of the object; and classifying, via the processor, the object based on the feature extraction.
