MONOPULSE ARRAY RADAR WITH SINGLE DIFFERENCE BEAM FOR SIMULTANEOUS AZIMUTH AND ELEVATION ANGLE DETERMINATION

摘要

A radar monopulse signal receiving system according toan aspect of the invention provides sum (.SIGMA.) and a single difference(.DELTA.)beam outputs from the beamformer. This is accomplished by encodingthe information relating to the azimuth and elevation difference beamsonto a single complex number. By comparison with some prior-artarrangements, the number of channels required for processing thesignals is reduced. Near the end of the monopulse processing, thequotient is taken of complex number divided by the sum beaminformation, which directly produces a complex monopulse ratiom=m A +jm E. The azimuth and elevation monopulse ratios arerepresented by m A and m E, respectively.
