AI Technical Summary

Technical Problem

Traditional guidance laws lack accuracy and sensitivity when facing high-speed and complex-moving maneuvering targets, especially in three-dimensional space, and have not been fully studied.

Method used

A three-dimensional virtual perspective maneuvering target guidance law based on a radar seeker is adopted. By establishing a three-dimensional relative motion model, setting the derivatives of the pitch and yaw virtual perspectives, obtaining acceleration instructions, and obtaining the guidance law through linearization processing, multiple aircraft can reach the target in a coordinated manner.

Benefits of technology

It provides more comprehensive and three-dimensional target information, ensuring that the aircraft can monitor the target position and movement changes in real time, improving the accuracy and stability of guidance, and especially maintaining target tracking and strike capabilities in an electromagnetic interference environment.

Abstract

The invention discloses a three-dimensional virtual visual angle maneuvering target guidance law based on a radar seeker. The three-dimensional virtual visual angle maneuvering target guidance law comprises the steps that a relative motion model with a virtual visual angle is established; the virtual view angle serves as an error angle, and derivatives of the pitching virtual view angle and the yawing virtual view angle to the missile-target distance are set; setting a virtual control quantity of yawing, and obtaining an acceleration instruction in the yawing direction based on a derivative of a pitching virtual view angle to a missile-target distance; a virtual control quantity of pitching is set, and an acceleration instruction in the pitching direction is obtained based on the derivative of the yaw virtual view angle to the missile-target distance; and linearizing the acceleration instruction in the yaw direction and the acceleration instruction in the pitching direction to obtain a guidance law. According to the guidance law disclosed by the invention, a three-dimensional virtual view angle technology is adopted, the guidance law provides more comprehensive and three-dimensional target information, and the comprehensive information can help the aircraft to better understand the position, attitude and motion trail of the target, so that guidance and strike are more effectively carried out.
