【摘要】 为改善以往模拟导弹位置角偏差信息信号方法存在成本高,电路复杂和扩展性不好的问题,在分析红外测角仪原理的基础上,给出了应用Multisim 10软件中的单片机进行模拟仿真的方案。设计出利用8052中用定时器进行计时的方式输出调频方波;调频方波脉宽的计算采用积分方法,并基于反馈的思想对计算结果进行修正。实验结果表明,系统能够精确地模拟出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。

【Abstract】 When checking the performance parameters of infrared angular instrument of a type of missile,it is necessary to simulate the signals of angular deviation of the missile position.The previous methods of simulating the signals of angular deviation of the missile position have many disadvantages,such as high cost,complicated circuit and bad expansibility.To improve these defects,a solution is provided using SCM of Multisim10 by analyzing the principle of the infrared angular instrument.The FM square wave is produced by the timer of the SCM of 8052 in the way of timing.The pulse width of the FM square wave is calculated using integral method and amended based on the idea of feedback.Experimental results show that the system can accurately simulate the signals of angular deviation generated by the infrared angular instrument when the missile is on the different positions of the optical axis.
