Abstract
Algorithms for obtaining estimates of the trajectory parameters of a m oving signal source for the case of one receiver and two spatially sep arated receivers are considered. The optimization algorithm is based o n the method of coordinate descent using a combination of the golden-s ection method and subsequent parabolic interpolation. For the interfer ometric scheme and moderate signal/noise ratios a distance estimation error of +/- (5-15%)%, a traverse time error of +/- (1-2) sec and a ve locity error of +/- (2-4)% are attainable.
