Abstract: A receiver system comprising: an input terminal configured to receive input signalling comprising a plurality of antenna-signals, wherein the plurality of antenna-signals each comprise information that corresponds to a first-frequency-bin and a second-frequency-bin. AoA-blocks can determine a first-angle-of-arrival and a second-angle-of-arrival associated with the first- and second-frequency-bins. A first-weighting-determination-block configured to, based on the first-angle-of-arrival and the second-angle-of-arrival, either: set first-weighting-values as values for constructively combining the information that corresponds to the first-frequency-bins of the plurality of antenna-signals; or set first-weighting-values as values for destructively combining the information that corresponds to the first-frequency-bins of the plurality of antenna-signals.

Abstract: Various embodiments relate to a bi-static radar system, including: first and second radar stations configured to: transmit first and second radar signals based upon a clock signal; wherein the first radar station receives a reflected second radar signal and the second radar station receives a reflected first radar signal; coherently process the reflected first and second radar signals to produce a first and second doppler frequency for first and second reference targets, wherein the first and second reference targets are is a detected target with the greatest signal strength; generate a frequency offset estimate based upon the average of the first and second doppler frequencies; frequency shift the reflected second radar signal by the frequency offset estimate to produce a corrected second radar signal; and coherently process the corrected second radar signal to produce first radar outputs from the first radar station.
