ABSTRACT:
Navigation systems which position one or more mobile platforms in real time with appropriate accuracy in reference to a known system of coordinates by the emission of signals into a propagation medium and processing them after detection are disclosed. Broad-band, broad-beam signals are employed. All received signals convey phase encoded angular coordinate information which characterizes the particular signal path. Phase encoding of angular information is effected by suitably configured "lenses" of dispersive materials or by post-critical angle reflection from a suitably configured reflector and shield combination. When the angular coordinate information is used in conjuction with range determinations from detected signals, an especially useful navigation system is provided which can operate from a single reference station.
