文提出了回路中含有硬件的仿真(hardware-in-the-loop simulation)方法,用于评价主动式导弹从发射前到截获目标的整个过程的性能。这套设备可用来进行系统的综合、设计验证、飞行前及飞行后的分析以及系统性能的复现。一台 CDC 公司的 Cyberl75通用计标机和 ADI 公司生产的一台多处理机系统联用,实现实时的六自由度仿真。这种仿真包括了目标模型、导弹模型以及它们的相对运动。Cyber175述通过一台 HP1000计算机驱动射频环境模型。射频环境模型给出必要的幅相控制,用以复现一个十点闪烁模型。这套设备还能接收主动辐射,给出距离、角度和速度各不相同的四个独立的回波信号。这套设备虽然尚未通过正式的鉴定程序,但模拟结果已与主动导弹的纯数字仿真进行了比较。和飞行试验结果的初步比较也说明了这套设备的可信度。
This paper presents a hardware-in-the-loop simulation method for evaluating the performance of active missiles throughout the entire process from launch to capture. The device can be used for system integration, design verification, pre-flight and post-flight analysis and system performance reappearance. A CDC Cyberl75 Universal Counting Machine and a multiprocessor system from Analog Devices implemented a real-time six-degree-of-freedom simulation. This simulation includes the target model, the missile model and their relative motion. Cyber175 describes an RF environment model driven by an HP1000 computer. The RF environment model gives the necessary amplitude and phase control to reproduce a ten-point flicker model. The device also receives active radiation and gives four separate echo signals with different distances, angles and velocities. Although this set of equipment has not yet passed the formal identification process, the simulation results have been compared with pure digital simulation of active missiles. The initial comparison with the flight test results also illustrates the credibility of the device.
