The invention r4elates to radar means for direction finding for radiant objects. Mono-pulse sum-difference direction finder for simultaneous measurement of angular directions to several radiant objects in one plane within main tab of radar antenna has high-frequency antenna system comprising of block of emitters, circular waveguide bridge, mirrors, receiver of sum channel, this includes mixer of sum channel, local heterodyne, amplifier of intermediate frequency of sum channel, first amplitude detector, receiver of difference channel, this includes mixer of difference channel, amplifier of intermediate frequency of difference channel, adding circuits. Direction finder has power divider, second amplitude detector, receiver of partial channel in set of mixer, amplifier of intermediate frequency, third amplitude detector, and first, second, third amplitude measuring devices, two calibration blocks, two blocks of comparison circuits, division device and respective joints. The invention provides decrease of error of measurement of angular direction of radiating objects. |
