Abstract

A high-resolution direction-finding method for active systems is presented. Unlike the available high-resolution method, which requires the number of coherent receiver channels to be larger than the number of targets, this method requires only two (three) channels for one (two)-dimensional direction-finding, regardless of the number of targets to be resolved, thus reducing the implementation cost. The idea of this method is to incorporate the signaling waveform information, available in the active systems, in using the signal-subspace processing approach
