INTERFERENCE WAVE ELIMINATOR

摘要

PURPOSE:To provide an interference wave eliminator having enhanced performance in which an erroneous target is not presented in the case of any target signal intensity and deterioration of performance can be localized only when the interference wave is prominent. CONSTITUTION:An output from an interference wave detecting circuit 120 is counted by an interference wave detecting times decision circuit 500 and an output therefrom is compared with a reference value by a comparing circuit 600. When the number of interference wave detection times is higher than the reference value, it is decided that the interference wave is prominent, and a detection threshold setting circuit 400 is controlled to elevate the detection threshold level of a target detection circuit 300.
