A direct data domain deterministic approach utilizing a nonuniform array to adaptively estimate the signal strength of an incoming signal in the presence of strong jammers, clutter, and thermal noise is presented. This method is based on choosing a weighted difference of neighboring antenna outputs, based on the direction of arrival of the signal of interest, in such a way that only the unwanted components remain. These unwanted signals are then nulled by adaptive weights. These weights are… CONTINUE READING
