Embodiment Construction

[0014] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below.

[0015] A kind of end-of-data-link guidance method for the seeker failure mode proposed by the present invention comprises the following steps:

[0016] S1. Use the medium guidance data link and missile navigation information to calculate the relative distance of the projectile and target, and judge whether the seeker is invalid. When the seeker is in an invalid state, send the failure flag to the launch platform according to the missile:

[0017] (a) Determine the position and velocity of the missile and the target in the line-of-sight coordinate system, and calculate the relative distance between the missile and the target

[0018] (b) When the projectile relative distance When it is less than the interception distance R of the seeker, the delay is 1s, the seeker sends the in...

Abstract

The invention relates to a data chain terminal guidance method in a seeker failure mode. The method comprises the following steps of firstly, judging the failure of a seeker; confirming the failure ofthe seeker, and switching from a midcourse guidance data chain to a terminal guidance data chain matching the update period of the seeker in real time; detecting and correcting the position and the speed of a target, in the terminal guidance data chain, in a sight line coordinate system through a missile flight control computer in real time; and solving the sight line angular speed in the sight line coordinate system and an overload command in a missile body coordinate system. According to the method, the motion information state of the target transmitted by the terminal guidance data chain with the high update rate is utilized to carry out guidance control over a missile with the failure of the seeker, and the problem that guidance command calculation cannot be carried out due to the failure of the seeker is avoided. The data chain information is used for solving, the guidance law is met, the failed missile is used for avoiding the huge loss caused by the scraping of the missile, andthe good effects are realized.

Description

technical field [0001] The invention belongs to the technical field of guidance control, and in particular relates to a data link end guidance method for a seeker failure mode, which is suitable for intercepting high-speed and large maneuvering targets in the air. Background technique [0002] Brand-new weapons and equipment and battlefield information environment have led to a brand-new combat mode, which indicates that the combat methods of modern warfare will undergo fundamental changes. Driven by information technology, the form of warfare is changing from mechanized warfare to informationized warfare, and the transformation from platform-centric to network-centric is a fundamental change in the military field under the background of informationized warfare. In the modern warfare environment characterized by informatization, tactical missiles will be subject to a variety of compound interferences such as infrared or electromagnetic. Under the constraints and influence of...
