红外导引系统快速原型仿真中的场景生成技术

介绍了基于Vega视景引擎红外场景生成方法，并应用于基于RT—LAB快速原型平台空空导弹红外导引系统快速原型仿真。设计了空空导弹红外导引系统快速原型仿真框架，根据框架建立了弹目6自由度运动学／动力学、红外导引系统Simulink仿真模型及目标等三维几何模型，采用Vega传感器模块和粒子系统模块实现目标各部件温度和干扰弹的自定义设置，同时针对快速原型实时仿真的要求设计了高精度的帧频控制方法。将红外场景生成软件与某空空导弹快速原型仿真系统进行联合仿真进行验证，对空空导弹导引系统的研制与开发起到了重要作用。

Scene Generation Technique of Rapid Prototyping Simulation using IR Guidance System

A method of the infrared scene generation based on Vega is described, and is applied to the rapid prototyping simulation of air- to- air missile IR guidance system. The rapid prototyping simulation framework is firstly designed, the geometric model of the target aircraft and the Simulink models of 6 de- gree equation of motion and IR guidance system are created, the infrared radiance control model and the infrared interference bombs are built base on the Sensor Vision system and particle system of Vega, and a high precision frame rate control method is presented. Finally, simulation is implemented together with the infrared scene generation software and the rapid prototyping system for validation.
