Abstract
PURPOSE:To acquire a ture target continuously by automatically detecting radio jamming etc. that try to jam a distance tracking system and transfering a target detecting gate with respect to these. CONSTITUTION:Whether tracking was made for an artificial target or not is decided by the change in the target speed detected with a target distance change rate calculating part 17. When a decision circuit 22 detects the acceleration exceeding the maximum acceleration in the distance direction that an ordinary target can take, it outputs positive or negative detection signals 28, 29. If there are these outputs, the true target signal left by the distance gate is detected with a gate circuit 18 or 19 and when coincide these detection signals 25, 26 with acceleration detection signals 28, 29, the distance tracking gate position is instantaneously moved to the position of the target detection gate 23 or 24, whereby the true target is automatically retracked.
