Abstract

PURPOSE:To make it possible to attain a target measurement angle of sufficiently high precision by using the imaginary part of a ratio of a difference signal to a sum signal for a monopulse tracking signal. CONSTITUTION:Sum signal SIGMA of received signals of divided partial array antennas is inputted to circuit 11, which outputs its amplitude ¦SIGMA¦. Sum signal SIGMA and difference signal DELTA are partially inputted to circuit 13, which outputs relative phase angle phi and circuit 14 outputs sinphi. This signal sinphi is multiplied by output ¦DELTA¦ of circuit 12 by circuit 15, which outputs ¦DELTA¦sinphi. Further, ¦DELTA¦sinphi is divided by ¦DELTA¦ by circuit 16 and ¦DELTA/SIGMA¦sinphi is finally outputted. This is used as an error signal of a monopulse.
