Evaluation of the efficiency of a two-position reception system using discrete algorithms in the frequency domain

A comparative evaluation of detection efficiencies for one-position and two-position reception systems has shown the significant advantages of the two-position systems in the presence of interference over the main lobes of the phased-array antenna radiation patterns. A method has been proposed for evaluating detection quality in a two-position system using discrete algorithms of spatial-temporal processing in the frequency domain. It is shown that this method can be used to assess the detection quality of multiposition multichannel reception systems in the presence of an arbitrary number of noise sources.
