Abstract:
An apparatus for mitigating the effects of multipath signals on a direct signal having a wavelength .lambda., said apparatus comprising:a reference antenna for acquiring the direct and multipath signals;a reference receiver connected to said reference antenna, said reference receiver for receiving the acquired direct and multipath signals and for providing a set of reference output data corresponding to the direct and multipath signals acquired by said reference antenna;a plurality of (m-1) secondary antennas disposed proximate said reference antenna, said secondary antennas for acquiring the direct and multipath signals;a plurality of (m-1) secondary receivers, each said secondary receiver connected to a respective said secondary antenna, said secondary receivers for receiving the direct and multipath signals acquired by said respective secondary antennas and for providing respective sets of secondary output data corresponding to the direct and multipath signals acquired by said respective secondary antennas; andcomputational means for receiving said reference output data from said reference receiver and for receiving said (m-1) sets of secondary output data from said secondary receivers, said computational means comprising means for solving simultaneous equations for processing said reference output data and said (m-1) sets of secondary output data to produce a set of multipath parameters.
