发明名称 SECONDARY RADAR TARGET DETECTION APPARATUS
摘要 <p>PURPOSE:To detect a target based on all of the signals received within the effective beam width of an antenna by performing the delay control of the termination detection in the azimuth direction of a target based on the magnitude relation between the run-length value of the target and reference value. CONSTITUTION:A target judging circuit 24, a run-length judging circuit 25 and a target detection unit 22 to which slight function is added are mounted. The judging circuit 25 compares the magnitude relation of an inputted run-length value 10 with a preset reference value and outputs a judging signal 13 to the circuit 24 as a control signal. The signal 13 becomes a '0' level at the time of run-length value > reference value and an inputted temporary termination signal 9 is outputted to a target report unit 26 as a real termination signal 12. At the time of run-length value < reference value, the signal 13 becomes a '1' level and the output of the signal 9 is prohibited at this time. This is the alteration only of the distance section where the target is present and entirely regardless of the other distance section.</p>
