MAXIMUM ENGAGEMENT DISTANCE CALCULATING METHOD BASED ON GRADIENT FOR AIR-TO-AIR MISSILE

The present invention relates to a method to calculate a maximum engagement distance for the launch of air-to-air guided missiles. According to a method to calculate a maximum engagement distance of air-to-air guided missiles, capable of determining whether a virtual target is shot down or not by launching a guided missile to the virtual target according to an initial condition, and launching the next guided missile by moving the position of a maternal body as much as an error distance in a line-of-sight direction when the shooting-down is failed, as the maximum distance is compensated by using inclination information between range-error coordinate values for the guided missiles, launched twice right before the failed of shooting-down, the number of repeating times and operation time are significantly reduced, as compared to the existing case.
