This paper presents the composition, operating principle, and test method of an advanced dynamic test platform used in infrared air-to-air missile guidance and control system. Then the key techniques including real time distributed simulation, SBS High-Speed Broadcast Reflective Memory, and design of simulation software are discussed in detail. For dynamic test, the combination of numerical real time and hardware-in-the-loop simulation technique for each guidance and control component is expatiated. Based on the test results for an infrared air to air missile guidance and control system and comparison with the field test data, it is indicated that this dynamic test technique and its environment could give a high accuracy verification system for the design improvement of infrared guidance and control systems. 提出了一种先进的红外空空导弹制导控制系统动态测试系统的组成、工作原理及测试方法,对于导弹动态测试过程中所采用的实时分布式仿真技术、SBS高速光纤反射内存技术以及仿真软件设计技术等关键技术内容进行了剖析,对于动态测试技术所能达到的导弹控制部件实物/数字实时半实物多重组合动态仿真技术进行了阐述。系统使用情况表明,该测试环境及动态测试技术可以明显提高导弹制导控制系统的研制手段及测试水平。 The generation way of pulse signal in IR seeker is important to control signal of Air to Air Missile(AAM).Based on signal generating principle of a certain type of IR AAM seeker,the authors compiled a simulating program for target image-point scanning with Visual C++ language and object-oriented technology,and made a simulation on computer for the processes of image-point scanning and pulse signal generating.The results showed that the program can substantially reflect the real image point scanning process and...
