Method and apparatus for radio location

摘要: This disclosure relates to multi-element antenna clusters or arrays for the reception and transmission of radio waves direction-finding, navigation aid emitter and/or receiver location purposes. In particular, it arrangements multiple antennas whereby direction propagation (arrival departure) a wavefront is determined from combination amplitudes phasor (or total individual output) differences between pairs antennas, said being along certain geometrical patterns, such as circle, an ellipse, polygon, open straight line, etc., with at least one longest dimension measuring more than wavelength incident departing wave. Although described in terms electromagnetic hence receiving sensors radiators, this invention reality applies any other form propagating waveborne energy, acoustic, ultrasonic, seismic, etc.
