Abstract

PURPOSE:To facilitate recovery of a flying body, to prevent leakage of a secrete, and to enable reutilization of the flying body by a method wherein after comple tion of test evaluation, the flying body for test evaluation is lowered as it is levitated by means of a shot down ineffective distance detecting signal. CONSTITUTION:When a distance between a target and a flying body for test evaluation exceeds a given value, a circuit 16 to detect a distance to target outputs a shot down ineffective distance detecting signal, and when the speed of the flying body is decreased to a value lower than given value, a speed detecting circuit 17 outputs an ineffective speed detecting signal. When a meeting time between a target and the flying body is below a given value, a meeting time detecting circuit 18 outputs an ineffective meeting time signal. An OR circuit 19 outputs a control signal when a shot down ineffective distance detecting signal, an ineffective speed detecting signal, or an ineffective meeting time signal is outputted, and the flying body is lowered as the flying body is levitated by means of a parachute 20. This constitution enables reutilzation of a flying body N' for test evaluation, and enables prevention of leakage of a secret since the flying body is recovered.
