某型导弹红外测角仪信号模拟研究

摘要

在对某型导弹控制箱的性能参数进行检测时,模拟红外测角仪所产生的导弹位置角偏差信息信号是必不可少的条件;在对红外测角仪原理分析的基础上,给出了FPGA设计方案,用QuartusⅡ软件对系统进行了仿真,用Altera公司的FPGA-EP2C35F672C6N对系统进行了硬件实现;实验结果表明,系统能够精确的模拟导弹在光轴不同位置时红外测角仪输出的导弹角偏差信息信号,每个信号周期误差达到了1μs.所产生的信号经调理电路送控制箱后能够被控制箱正确识别.%When checking the performance parameters of the control instrument of a type of missile, it is necessary to simulate the sig nals of angular deviation of the missile position. A solution is provided using FPGA by analyzing on the principle of the infrared angular instrument. Quartus Ⅱ software is used to simulate and the FPGA—EP2C35F672C6N is used to apply the system. The results show that the system can simulate the signals of angular deviation generated by the infrared angular instrument precisely when the missile is on the different positions of the optical axis, and the error of every cycle is 1μs. The signal simulated can be recognized by the control instrument correctly.
