Guidance method with ballistic angle constraint

Abstract

A missile terminal guidance method, comprising the following steps: first establish the relative motion equation between the missile and the target, and consider the influence of the target maneuvering acceleration in the equation; Combined with the projectile-target relative motion equation, the guidance law is designed, and the switching items in the guidance law are further corrected to overcome the influence of target maneuvering. The invention can greatly improve the adaptability of the guidance system to the maneuvering acceleration of the target, and can ensure that the missile has an expected ballistic angle when hitting the target, thereby improving the degree of damage to the target, and can independently determine the guidance parameters online, simplifying the design The process reduces the design workload and improves the robustness of the guidance system.

Description

technical field The invention relates to a missile guidance method, which can ensure that the missile has an expected ballistic angle while hitting the target, thereby solving the problem of deep damage to the target. Background technique The present invention aims at the requirements of the missile to deeply damage the target, relies on the guidance method to ensure that the missile has the expected ballistic angle when hitting the target, and can improve the strike accuracy of the guidance system to the maneuvering target, and can independently determine the guidance parameters online, which simplifies the design The process reduces the design workload, overcomes the defect that the passive detection device can only measure distance and speed, and improves the robustness of the guidance system to check the adaptability of the target maneuvering acceleration. Contents of the invention Technical solution problem of the present invention: Aiming at the shortcomings of ex...
