实物在回路中的仿真已被用来估计主动制导导弹从发射前到拦截的性能。本装置可用于导弹系统综合、设计检验、飞行前和飞行后分析以及系统性能的论证。美国控制数据公司(CDC)的赛伯(Cyber)175通用计算机和国际应用动力学公司(ADI)AD-10多用途处理机的结合,解决了六自由度实时仿真问题。该仿真包括了目标模型、导弹模型和它们之间的相对运动。赛伯(Cyber)175还通过哈莱特帕卡德(HewlettPackard)公司HP1000计算机驱动射频环境模型。射频环境模型提供了必需的相位和振幅控制,以重新产生一个共有10个点的反射模型。本装置也能接收主动制导导弹发射的电波和提供四个在射程、角度和速度上互相分隔开的独立回波。该仿真装置虽没有经过正式生效计划的考验,但是使用本装置得到的结果已能同主动制导导弹纯数学仿真的结果相比较。与飞行试验结果的初步比较,证明了本装置的可靠性。
The physical simulation in the loop has been used to estimate the performance of a proactively guided missile from launch to interception. The device can be used for missile system synthesis, design verification, pre-flight and post-flight analysis and system performance demonstration. The combination of Cyber 175 Universal Computer with ADI AD-10 multipurpose processors from US Controlled Data Corporation (CDC) addresses six-DOF real-time simulation issues. The simulation includes the target model, the missile model and the relative motion between them. The Cyber 175 also drives the RF environment model via the Hewlett Packard HP1000 computer. The RF environment model provides the necessary phase and amplitude control to recreate a total of 10 point reflection models. The unit also receives radio waves from active guided missiles and provides four independent echoes separated from each other in range, angle and speed. Although the simulation device did not pass the formal validation test, the results obtained with this device have been compared with the results of the purely mathematical simulation of the active guidance missile. The preliminary comparison with the flight test results proves the reliability of the device.
