PURPOSE:To simplify the detection of an object and the measurement of the bearing and distance by optionally dividing a display screen into a correlation processing signal display area and a non-correlation processing signal display area. CONSTITUTION:A range setting circuit 1 sets up a range for correlation processing relating to the distance and bearing. A distance coincident circuit 2 compares the set-up distance range with an output from a distance counter 4 and detects whether the distance to be displayed on a CRT11 is included in the set range or not. The bearing is also detected in the same procedure. Receiving the distance and bearing detecting signals, a signal processor 8 executes the correlation processing of a receiving signal 110 when both the detection signals are coincident with each other, and outputs the receiving signal as it is if both the detection signals are inconsistent. Since the CRT display surface can be optionally divided into the correlation processing signal display area and the non-correlation signal processing area, it is easily possible to detect the object and measure the bearing and distance. |
