Various techniques are provided to efficiently detect the position of an object relative to a compact radar system including a transmitter antenna array and a receiver antenna array. In one example, a method includes designating a plurality of transmitter and receiver channels for a transmitter antenna array and a receiver antenna array of an object sensing system, scanning the transmitter antenna array and the receiver antenna array through the designated channels to measure channel responses corresponding to each one of the designated channels, and determining a directional vector to or from an object scanned by at least one of the designated channels based, at least in part, on the measured channel responses.
