Abstract:A single-output array receiver based on static antenna elements of arbitrary geometry that drive linear, time-invariant signal processing is well known to be fully characterized by a frequency response dependent on direction-of-arrival (DOA). This paper develops the generalized characterization that results when the time-invariance requirement is removed. The special case based on periodically varying signal processing is further derived and shows such a system to be fundamentally, structurally incapable of re… Show more
