Abstract

PURPOSE:To erase te mobile clatters without lowering the phase shift precision and phase shift speed, by correcting the phase of the clatter reflection signals in the video signals by means of phase difference signals at every cycle of the repetitive pulses detected by the reflection signals. CONSTITUTION:The signals received by the antenna 1 are converted through the switch 2, mixer 4 and the I/Q phase detector part 14, to the video signals having phase informations. These video signals are forwarded through the A/D converters 16, 17 to the phase correction signal generating part 18 and the phase correcting part 19. The output of the phase correcting part 19 is introduced to the output end through the erasing part 36 where the reflection signals from the mobile clatters are erased and the D/A convertor 38.
