This coincidence signal becomes a clock input of a DFF15 through a gate 14. When a sweep is executed again and the contents of the counter 8 reach the upper limit, the coincidence signal is outputted again. As a result, a -Q output of the DFF15 is varied to a high level from a low level, the DFF16 is set to a low level, the gate 17 becomes a low level, and the receiving sensitivity setting circuit 1 is set to the second sensitivity of higher sensitivity.
