Abstract

PURPOSE:To make it possible to easily discriminate a desired target in sporatic clutter districts by obtaining the mean value of Doppler deviations in correspondence to scanning in every specific region, and compensating the Doppler deviation at the front step of the erasing circuit. CONSTITUTION:With respect to a received IF signal V sent from a radar receiver via an input terminal 1, the Doppler deviation phase phid between sweeps by a phase detecting circuit 4. The Doppler mean value phidn within the region is obtained by a mean circuit 5, and supplied to a memory 6 further the mean value being accumulated in an accumulator 7. In a phase-shifting circuit 12, the Doppler deviation is crased by the output of the accumulator 7. Furthermore, in an erasing circuit 10', the clutter signal is erased.
