Abstract

The method involves determining a level of group signals in relation to bearing angles. The bearing angles that correspond to maximum level are outputted as target bearing. A set of time-delay coefficients is empirically determined and stored for each carrier-based bearing angle, where the coefficient is assigned by a transducer (13) of a receiving antenna (11). The carrier-based bearing angle is calculated for north-referred bearing angle with heading of an antenna carrier. The coefficients are used on the receiving signal.
