<p>PURPOSE:To prevent a mistaken target from being increased by inputting a transmission blank signal in a microcomputer and not using the calculation of detection probability as to a sweep in which transmission blank is applied. CONSTITUTION:As to a rader target detecting circuit, a hit which is regarded as the output of a Constant False Alarm Rate (CFAR) quantization circuit 1 is counted by a CPU 8 in the microcomputer 2 and also the number of sweeps within an unit area exclusive of the sweeps in which the transmission blank is applied after receiving the transmission blank signal 12 is counted. And then, the detection probability per unit area is detected. The number of cells per unit area is calculated by multiplying the number of range cells between alphaNM by the number of the sweeps in the unit area. Since then, the action by the computer 2 and the action by the circuit 1 are the same as usual.</p> |
