Semi-physical real-time simulation system of laser guided missile

Abstract

The invention discloses a semi-physical real-time simulation system of a laser guided missile. The system is used for carrying out simulation test on a missile laser guide head, an electric steering engine and a missile guidance control algorithm. The system comprises a signal simulation part used for generating the laser received by a simulation guide head, a motion simulation part used for simulating the relative motion relation between a missile and a target; a test main control part used for running the missile motion simulation software in real time, driving the whole simulation system, monitoring and recording data in the whole test process, and analyzing the data. The method aims to provide an auxiliary design tool for missile designers, so that designers can know problems possiblyexisting in the missile performance and design. The development period of missiles is shortened, and the number of external field flight tests is reduced. The system has better practicability and higher economic benefits.

Description

technical field [0001] The invention relates to laser-guided missiles, and particularly discloses a half-physical real-time simulation system for laser-guided missiles. Background technique [0002] Laser-guided missiles are launched from fixed-wing aircraft, rotary-wing helicopters or drones. When the ground soldier or aircraft pilot finds the target, the missile and carrier aircraft are notified to enter the ready state. After the missile meets the launch conditions, the missile is launched. At the same time, the ground soldier or carrier aircraft uses the laser irradiator to irradiate the target. After the missile enters the target acquisition area after passing through the initial guidance and intermediate guidance sections, when the missile approaches the target so that the seeker can receive the laser signal reflected from the target, the seeker unlocks and starts to track the target, and the missile enters the final guidance section. And hit the target. [0003] The...

AI Technical Summary

Problems solved by technology

In order to ensure real-time performance, the missile motion simulation software generally needs to be written in C language, the development cycle is long, and each function needs to be tested to ensure that the software execution time meets the real-time requirements

In addition, the actual missile development process may often need to modify the overall parameters of the missile and the guidance control algorithm, which increases the complexity of the maintenance of the missile motion simulation software
