Air-to-ground guided weapon lateral attack method and device

Abstract

The invention discloses an air-to-ground guided weapon lateral attack method and device, wherein the method comprises the following steps of acquiring an attack target position, a preset lateral constraint angle psi c and a real-time flight state of an aircraft, wherein the flight state comprises a position, a speed and a wind field condition of the aircraft; according to the flight state and thepsi c, determining a virtual target position in a manner of trajectory simulation iterative calculation; then furthermore, determining a flight trajectory of the guided weapon according to the virtualtarget position, the attack target position and the flight state; and according to the flight trajectory, after the guided weapon flies to the virtual target position after being launched, starting aturning program, and then performing lateral attack on an attack target according to the psi c. the air-to-ground guided weapon lateral attack method and device solves the technical problem that thelateral attack capability of the weapon cannot be well achieved due to limitation of a projectile body in the prior art.

Description

technical field [0001] The invention belongs to the field of guidance and control, and relates to a method and a device for lateral attack of an air-to-ground guided weapon. Background technique [0002] In modern warfare, air-to-ground guided weapons can attack targets in many ways, and lateral attack is one of the important attack methods. In related technologies, the lateral attack of the weapon is mostly realized by using the optimal guidance rate, but due to the limitation of the overload of the projectile itself, this method cannot maximize the lateral attack capability of the weapon, and this method can only ensure that when the projectile meets the target Due to the angle constraints, the angle of view before encountering, the remaining flight distance and other indicators cannot be adjusted and controlled, which brings difficulties to the use of air-to-ground guided weapons equipped with seekers. [0003] For the above problems, no effective solution has been propo...
