1. A computer implemented method for processing radar reflections, the method comprising:
receiving radar reflections by at least one radar sensor;
determining a target angle under which radar reflections from a potential target are received by the at least one radar sensor;
determining a target angle energy and a Doppler frequency of the radar reflections received by the at least one radar sensor at the target angle;
determining a velocity of the potential target based on the Doppler frequency of the radar reflections recited by the at least one radar sensor at the target angle;
determining a region of interest including the target angle and an angular region on each side of the target angle;
determining a Doppler frequency region that corresponds to a predetermined velocity region around the velocity of the potential target;
determining an energy of radar reflections received by the at least one radar sensor within the Doppler frequency region at each of a plurality of angles within the region of interest including the target angle and the determined angular region on each side of the target angle;
determining a total accumulated energy in the region of interest and within the Doppler frequency region by summing the target angle energy and each of the energies of the radar reflections within the Doppler frequency region at the plurality of angles within the region of interest; and
at least one of detecting and classifying the potential target based on the total accumulated energy in the region of interest and within the Doppler frequency region.
