Abstract

PURPOSE:To improve the target-detecting performance by a method wherein the selection of the detection base K/W of the sensitivity of a receiver within a tracking gate, the signal detection algorithm of a synchronization signal detection sircuit, etc. is separated from other areas and is controlled independently. CONSTITUTION:By feeding back a target estimating and tracking gate information from a tracking circuit to the STC circuit of the receiver, the synchronization signal detection circuit 17 and a sweep correlation operating circuit 18, control is performed so that the STC circuit of the receiver raises the sensitivity of the receiver only within the tracking gate, that the synchronization signal detection circuit 17 changes the detection algorithm to another algorithm and removes a nonsynchronization signal, picking up an effective signal in a low hit pattern and that the sweep correlation operating circuit 18 changes the detection base K/W to detect the target when a machine whereon the mode C is not yet mounted is estimated as the target. By such a constitution, a signal is detected adaptively only of the area getting into the tracking gate, whereby the disappearance of the effective signal is prevented and thus the target-detecting performance can be improved.
