Near-far field multipath spatial-temporal localisation

Abstract

In this paper, a passive array processing algorithm is proposed for localising the near-far field multipaths of the desired signal in the presence of co-channel interference. By expressing the unknown path delay as a function of the path's range, the proposed spatiotemporal localisation algorithm estimates the locations of all the multipath reflectors of the desired signal source using a subspace-type cost function. The performance of the proposed algorithm is evaluated through computer simulation studies.
