Multi-missile cooperative attack guidance law designing method

Abstract

The invention provides a multi-missile cooperative attack guidance law designing method. The method specifically includes: step 1, in a front flying section, controlling flying of missiles according to a missile-target distance cooperative guidance law; namely, taking a normal acceleration an of each missile as a control variable to control speed directions of each missile to enable the missile-target distance r of each missile to be converged within an expected missile-target distance; and step 2, in a tail flying section, controlling flying of the missiles according to a line of sight (LOS) speed convergence guidance law; namely, taking the normal acceleration an of each missile as the control variable to control the LOS speed of each missile to be quickly converged to be zero within a limited time to enable the missiles to hit a target finally. By the multi-missile cooperative attack guidance law designing method, each missile can be guaranteed to hit the target almost at time same time, multi-missile saturation attack can be realized, and penetration ability can be greatly improved.

Description

technical field [0001] The invention relates to a guidance law design method for realizing coordinated missile-to-target distance and attack time when controlling a plurality of guided missiles for coordinated operations, and belongs to the technical field of guidance. Background technique [0002] The Close Defense Weapon System (CIWS) is a kind of equipment attached to naval ships, which is used to detect and destroy approaching anti-ship missiles or related threat aircraft, and has powerful power. In order to effectively break through the interception of CIWS, anti-ship missiles usually adopt saturation attack tactics. Saturation attacks generally require missile groups to arrive at the target area at the same time and finally hit the target almost simultaneously. If the two "simultaneous" cannot be achieved well, it will become more difficult for the missile to break through the enemy's CIWS, and the saturation attack will lose its original meaning. Therefore, how to f...

Problems solved by technology

However, during the flight of the missile, its flight speed is generally not a fixed value, and the estimation accuracy of the remaining flight time is difficult to guarantee.

At this time, the existi
