Abstract

A radar sensor includes: a transmitter configured to transmit radar via a transmit antenna; a receiver configured to receive signals reflected back to the radar sensor via a receive antenna; a profile module configured to generate an energy profile including a plurality of points for a plurality of distances from the radar sensor, respectively, each of the points including an energy of the signals reflected back to the radar sensor for that one of the plurality of distances; a minimums module configured to identify ones of the plurality of points having local minimums of energy; and a curve module configured to, based on the plurality of points having local minimums of energy, generate an equation representative of a curve fit to the plurality of points having local minimums of energy, the equation relating distance from the radar sensor to baseline energy of the signals reflected back to the radar sensor.
