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 ...
A system for receiving electromagnetic radiation, which may be subject to environmental perturbations, and producing a system output that is substantially unaffected by the perturbations, said system comprising: antenna means for producing an antenna output in response to received electromagnetic radiation that may be affected by the perturbations; data storage means for storing information relating to the effect of the perturbations on electromagnetic radiation received by said antenna means, the information being based upon a frequency-scaled analysis ...
