ABSTRACT:
A process is disclosed for discriminating between received ranging signals, such as GPS, GNSS, and radar signals, which arrive via a single path and those which arrive via multiple paths. The number of paths is also estimated. This is accomplished by comparing the residual for an ithorder ML estimator of signal time of arrival, where order refers to the number of signal paths for which the estimator is optimal, to a discriminant determined either analytically or empirically and deciding that i distinct signal path components are present in the observation of the signal if for all kthorder estimators where k<i, the residual is greater than the discriminant for that order estimator and the residual of the ithorder estimator is not greater than the discriminant for that order estimator. The invention is particularly useful in obtaining an appropriate signal model for model-based estimation methods.
