A vehicle or other mobile communication entity () locates objects using received (typically radio frequency) signals (). These received signals included multi-path versions of the transmitted signals (). The received signals may include packets having location information of the transmission source. The receiving vehicle may track, or know, its own position. The receiving entity may determine properties for a multi-path version of the signal (). These properties may include a delay, a Doppler and an angle of reception () for one or more multi-path versions of the received signal. The receiving entity may also measure an imbalance () induced between a pair (or more) of antenna elements () for a particular multi-path version of the signal received. This imbalance may be dependent on the angle of arrival of the particular signal being received. In some embodiments of the invention, the measured imbalance includes two parts: a delta phase (dPhase,) and a delta Gain (dGain,). These delta values may be considered as a complex number with phase dPhase and magnitude dGain.
