PROBLEM TO BE SOLVED: To provide a missile which can approach to a target from the direction having strong scattering intensity of a radio wave around the target. SOLUTION: The missile 3 includes: a steering device 12; a receiving part 7 for receiving reflected waves of radio waves reflected by a target aircraft 2; a target detector 8 capturing and following the target aircraft 2 based on the detection wave output and calculating an angle measuring signal to the target direction; an inertia device 13; a direction estimating device 9 for calculating the position and speed of the target aircraft 2 and estimating and computing a flight route toward the direction of a junction point between the missile 3 and the target aircraft 2, based on the flight position, flight speed and the initial position and initial speed of the target aircraft 2 stored beforehand; and a guidance treater 11 for performing guidance calculation and outputting a steering signal with respect to the steering device 12. The direction estimating device 9 finds a straight line D extended to the direction having strong scattering intensity of scattered waves on a face A vertical to the ground surface including the target position and a radio wave transmitting source 1, and calculates a passage point of the missile 3, based on the straight line D and the position of the target aircraft 2. The guidance treater 11 calculates the steering signal related to the passage point. COPYRIGHT: (C)2010,JPO&INPIT |
