Abstract
PURPOSE:To prevent the overflow of computer input due to an increase in the number of clutter holes, by controlling and setting a threshold value for detecting a target so that the detection number of targets within a clutter region is received within a predetermined range. CONSTITUTION:A target detection level control signal generating circuit 26 sends a control signal raising a threshold value for detecting a target to a target detection level generating circuit 24 when scanning wherein the average detection number of targets exceed the upper limit value 28 reaches a predetermined number of times or more. When the scanning wherein the average detection number of targets not exceeding an average detection number lower limit value 29 reach a predetermined number of times, a control signal lowering the threshold value is sent out to the circuit and, when said average detection number of targets are within a range of the average detection number lower limit value 29 and an average detection number upper limit value 28, a control signal setting the threshold as it is sent out to the circuit 24. As mentioned above, by controlling the threshold value so that the detection number of targets within a clutter region are received within a predetermined range, the overflow of computer input is prevented even when the amplitude characteristic of clutter is varied.
