ABSTRACT:
A system and method for tracking a remote RF transmitter with reduced susceptibility to the effects of multipath in which the distance and direction of an arriving RF chirp signal are determined with respect to the earliest arriving portion of the signal which is presumed to be the direct path signal. The received chirp signals, including the direct and multipath signals, from a remote transmitter are correlated into plural path signals, and the direction and distance to the transmitter is determined from the earliest arriving path signal.
