Abstract

A semi-physical simulation system for developing a laser terminal guidance ammunition round comprises a rocket sled test platform, a target simulation device, an attitude simulation device and a simulation platform. The rocket sled test platform launches a rocket sled loaded with a target and measures speed and position information of the rocket sled in real time. The target simulation device utilizes laser to irradiate the target to enable a seeker of the laser terminal guidance ammunition round to be capable of receiving laser from the target to perform target tracking. The attitude simulation device comprises a three-axle rotary table capable of loading the seeker and is used for simulating attitude movement of a missile body. The simulation platform analyzes and processes the speed and position information of the rocket sled and a seeker generating signal according to a preset simulation mathematical model to obtain information related with attitude change of the missile body and relative movement of a missile and correspondingly controls the rotation of the three-axle rotary table. The rocket sled test platform is located outside the outdoor, and the rocket sled test platform and the simulation platform perform data transmission through a radio station and achieve time synchronization.

Description

technical field [0001] The invention relates to the development of laser terminal guided projectiles, and particularly discloses an indoor and outdoor combined semi-physical simulation system for developing laser terminal guided projectiles. Background technique [0002] Semi-physical simulation refers to the simulation of part of the real object connected to the researched system in the simulation circuit of the simulation experiment system. The term "semi-physical simulation" is a popular and customary name for this type of system simulation method and corresponding simulation system in the domestic simulation circle. Its accurate meaning refers to "hardware in the loop". Simulation, HIL S)". [0003] The research and development of guided weapons has accelerated the process of guidance of conventional weapons, but the price of guided weapons is much higher than that of ordinary conventional weapons due to the guidance precision components such as seekers, autopilots, and...
