A multi-bomb time coordinated missile guidance method and system

Abstract

The invention discloses a multi-bomb time coordinated missile guidance method and system. The method comprises the following steps: (1) establishing the guidance kinematics model of each missile in the missile group; The guidance kinematics model provides the CPN guidance law for stationary targets and maneuvering targets respectively, and completes missile guidance based on the CPN guidance law; wherein, when the CPN guidance law is determined, the projectile group consistency expectation is calculated based on the weighted average consistency method Remaining flight time; based on the multi-agent deep deterministic policy gradient algorithm, the missile learns the correlation coefficient of the CPN guidance law. The invention applies the multi-agent DRL on the basis of the existing time cooperative guidance law CPN to endow the missile group with intelligent perception and decision-making capabilities, which can improve the guidance accuracy, reduce the coordination time error, and realize effective attacks on stationary and maneuvering targets respectively.

Description

technical field [0001] The invention belongs to the technical field of missile guidance, in particular to a missile guidance method and system with multi-bomb time coordination. Background technique [0002] In the past few decades, the classical proportional navigation guidance (PNG) has been widely used and studied in engineering because of its simple implementation and good guidance effect. With the development of missile defense systems, especially defense penetration systems, many new modes of missile-guided operations have emerged; for example, multi-missile salvo attacks can effectively increase the survival probability of a single offensive missile, thereby completing predetermined combat tasks. Multi-missile salvo attack refers to multiple missiles attacking the same target at the same time. Compared with single missile combat, the damage efficiency of the target can be greatly improved. [0003] The main method to achieve multi-missile salvo attack is to control t...

AI Technical Summary

Problems solved by technology

[0007] (1) Most of the existing time-coordinated guidance laws are the product of the combination of PNG and advanced control theory, which are not considered from the perspective of intelligent perception and decision-making, and most of them are aimed at stationary targets;

[0008] (2) In the field of missile guidance, DRL is currently mostly used in the improvement of the guidance accuracy of a single missile and the offensive and defensive confrontation between interceptor missiles and penetration missiles. It has not been applied to multi-missile time coordinated guidance
