ABSTRACT:
A system is disclosed in which a direction-finding system (12) employed on an aircraft (20) receives RF transmissions from a remote signal source (16). Amplitude and phase data concerning the transmission are used for direction finding but are perturbed by the various surfaces of the aircraft. To minimize the influence of such perturbations, a database (14) including model data subject to the same perturbations is employed by the system and incoming transmissions from signal source (16) are correlated to the database data to determine the proper azimuth and elevation associated with said transmissions. Several embodiments of a database production system (18) used in creating the database are also disclosed.
