Abstract

PURPOSE:To increase the range of a tracking angular velocity by adding a means for compensating angle error signal characteristics regarding a target. CONSTITUTION:A reflected wave 1 from a target is received by antennas 2, and hybrid circuits 3 extract a sum and a difference signal from the received signal. Those signal are converted by mixers 4 into IF signals, which are amplified by IF amplifiers 6 and inputted to a phase detecting circuit 7 while inputted to a level comparator 9. The output of the level comparator 9 is processed by a coefficient setting circuit 10 and a multiplier 11, whose output is supplied to the phase detecting circuit 7. The output of the phase detecting circuit 7 drives servomechanism 8 to direct the antennas to the target.
