Guidance method for short-range air-to-ground missile mixed program-controlled terminal guidance section

Abstract

The invention relates to a short-range air-to-ground missile mixed program-controlled section + terminal guidance guidance technology, which is characterized in that: after the missile is launched, the air trajectory is divided into three sections: a program-controlled section, a transition section and a terminal guidance section. Introduce the control law in the program-controlled section, optimize the trajectory of the program-controlled section, and improve the maneuverability of the missile. A transition section is set between the program control section and the terminal guidance section, so that the program control section and the terminal guidance section can be handed over smoothly, and when the guidance signal is introduced, it will not cause excessive self-excited oscillation of the missile body. In the final guidance stage, a specific guidance law is used to guide the missile close to the target until it hits the target. On the basis of this three-segment flight trajectory, specific adjustment parameters can be set to optimize the entire trajectory of the trajectory to meet the attack requirements.

Description

Guidance method for terminal guidance section of short-range air-to-ground missile mixed program-controlled section Technical field The present invention relates to a kind of short-range air-to-ground missile hybrid program-controlled segment+terminal guidance and guidance technology, which can solve the problem of air trajectory optimization problem and meet the requirements of attack target conditions. Background technique The present invention is aimed at a class of short-range air-to-ground missiles, after its launching, thrust only maintains several seconds, and projectile body is before hitting target. During the remaining period of time, relying on a certain guidance scheme to achieve the attack target requirements, the flight parameters of this missile vary greatly, especially It is the effect of speed change. It should be ensured that the impact on the system is small before and after the power is on, and the speed must be guaranteed before hitting the target. ...
