Injection-type semi-physical simulation system for laser-guided missile

Abstract

The invention provides an injection-type semi-physical simulation system for a laser-guided missile, and belongs to the technical field of laser-guided missile development. In order to overcome the projection diffuse reflection type defect, the system comprises a simulation platform, a missile guider, a guidance, navigation and control (GNC) system, a target simulation device, a posture simulation device, an acceleration simulation device, a load simulation device and a launch-control device. The simulation platform mainly undertakes building and calculating of all mathematical models and is communicated with other equipment participating in simulation. The missile guider receives a laser signal sent from the target simulation device to form light spot gravity center location information, and a target orientation is supplied to the GNC system through a control area network (CAN) bus network. The GNC system is installed on the posture simulation device. Light emitting from the target simulation device is injected into the missile guider to simulate target movement. The posture of the missile is simulated through the posture simulation device, and the angular motion characteristics of the missile in the air are reproduced. Output of an accelerometer is simulated through the acceleration simulation device. The load simulation device is used for simulating the aerodynamic moment on a steering engine in the flying process of the missile. The launch-control device mainly completes self-checking and confirming of equipment, data loading and launching instructions on the missile.

Description

technical field [0001] The invention relates to an injection-type semi-physical simulation system for developing a small laser-guided missile, belonging to the technical field of laser-guided missile development. Background technique [0002] Semi-physical simulation refers to the simulation of inserting part of the physical object into the simulation loop of the system. Hardware-in-the-loop simulation can improve the authenticity of guided weapon simulation experiments and reduce the experimental cost of weapon systems. Compared with conventional weapons, guided weapon systems include seeker, navigation guidance and control system (hereinafter referred to as GNC system), engines, steering gear and other components, and the cost of flight experiments is very expensive. The use of hardware-in-the-loop simulation experiments can greatly reduce the number of flight experiments and reduce the cost of experiments. Compared with other simulations, hardware-in-the-loop simulation...
