Abstract

PURPOSE:To set an optional range as a warning range by sending a warning signal out of a data comparison part when a received signal indicates a detection point is within the warning range and there is a target at the detection point. CONSTITUTION:A distance clock 111 sent out of a clock generation part 11 is inputted to a distance counter 12 and a distance signal 121 generated by the counter 12 is supplied to a data ROM. Further, an azimuth pulse 142 and a bow line signal 143 from an antenna are led to an azimuth counter 14, and an azimuth signal 141 generated by a counter 14 is inputted to a ROM 16, whose output is inputted to the data comparison part 18 through a gate part 17. Further, the comparison part 18 inputs a received signal 181 indicating whether or not there is a target. Then when the signal 181 indicates that the detection point is within the warning range and there is the target at the detection point, the comparison part 18 considers that the target enters the warning range and outputs a warning signal 182 to a warning generation part 19. Thus, an optional range can be set as the warning range.
