Abstract
PURPOSE:To exellently erase a clutter by obtaining the mean value of Dopper deviations in correspondence to scanning in every specific region, and selectively setting the shaping degree of the amplitude response characteristic adapted for the expansion of clutter spectrum distribution existing within the region. CONSTITUTION:With respect to a received IF signal V sent from a radar receiver via an input terminal 1, the adsolute value ¦phid¦ of a Doppler deviation phase between sweeps is obtained by a phase detector 21. The Doppler deviation phase mean value phidn within the region is obtained by a mean circuit 22 and it is supplied in a memory 23. The shaping degree of the amplitude response characteristic is determined in a feedback constant switching device 13' of an eraser 10' by a control signal due to the output phid(n-1) of the memory 23 thereby to switch the feedback constant. The eraser 10' erases the clutter signal having a desired Doppler deviation by the amplitude response characteristic adapted for the extension of the spectrum distribution.
