以末敏弹为研究对象,采用半实物仿真技术,设计了末敏弹红外敏感器室内半实物仿真系统,整个系统利用Multi-Gen Creator建立场景模型和目标的三维几何模型,利用Vega产生红外敏感器探测视场的数字场景,并将末敏弹的探测系统?红外敏感器作为实体引入到仿真系统参与试验,并和其它物理模型、数学模型构成闭合回路,完成了末敏弹的实时仿真功能。最后,通过仿真测试数据库对其探测系统性能进行了分析评估,该系统具有误检率和漏检率低的优点,并对漏检的原因进行了分析。

A method of hardware- in- the- loop simulation system for infrared sensor of terminal sensitive projectile is presented. The terrain model and 3D geometry model of target are set up by Multi - Gen Creator software, digital scene of infrared sensor is generated by Vega Prime software in system, and as an entity, the detection system of terminal sensitive projectile is introduced into simulation system, and a closed path is constructed with other physical and mathematical models, and the real - time simulation is completed. At last, detection performance of infrared sensor is discussed and evaluated. The experimental results show that the detection error rate and false - negative rate are low, and the reason of false - negative is discussed.
