<p>PURPOSE:To make an electric wave passive guided missile fly in the target direction in the case strong radiant waves are radiated while the missile is guided, by a method wherein a receiver saturated state detecting circuit detects a saturated state of a receiver and target direction signals are generated from a receiver saturation/electric wave stoppage period target direction signal generating device. CONSTITUTION:A receiver saturation detecting circuit 25 outputs low-level (high-level) signals until the input level to a receiver 4 exceeds a specified level and then high-level (low-level) signals in the case the input level to the receiver 4 exceeds the specified level. When an OR circuit 26 outputs high-level (low- level) signals in the case either of outputs from an electric wave stoppage detecting circuit 17 or the receiver saturation detecting circuit 25 is high-level (low-level), a receiver saturation/electric wave stoppage period target direction signal generating device 24 generates target direction signals according to error signals at the time of saturation of the receiver 4 and output signals of an inertia navigation device 5, and when the OR circuit 26 outputs low-level (high- level) signals, the receiver saturation/electric wave stoppage period target direction signal generating device 24 does not output signals.</p> |
