摘要
A radar monopulse signal receiving system according to an aspect of the invention provides sum (Σ) and a single difference (Δ) beam outputs from the beamformer. This is accomplished by encoding the information relating to the azimuth and elevation difference beams onto a single complex number. By comparison with some prior-art arrangements, the number of channels required for processing the signals is reduced. Near the end of the monopulse processing, the quotient is taken of complex number divided by the sum beam information, which directly produces a complex monopulse ratio m=mA +jmE. The azimuth and elevation monopulse ratios are represented by mA and mE, respectively.
