PURPOSE:To improve the hitting accuracy by changing the navigation of a flying object in response to the distance between said flying object and a target moving at a high speed. CONSTITUTION:Both direction and position of a target moving at a high speed, e.g. an air missile, etc. are detected, and then a flying object is guided to the target by the detection signal. In this case, the changing factors deltaS of viewing angle is detected by a tracking seeker 10, and the control signal is obtained by relay switches 17 and 18 through the 1st or the 2nd navigation control means 19-21. This control signal is impressed to a steering servo 22 to drive an actuator, and the flying route of the flying object is changed for guidance. For the control means of this navigation, the changing factor deltaS and the distance rS obtained by a radar telemeter 13 are compared with set values S0 and S1-S2 through A/D converters 12 and 15. Then the proportional navigation control method is used with an amplifier 19 and a limiter 20 in case the distance rS is large or extremely small. Otherwise the relay switches 17, 18 are changed over to use another navigation control with which a bang-bang element 21 is applied or the gain of the control system is greatly increased. |
