摘要

摘要: 介绍了激光驾束制导仪中调制盘的空间编码原理,阐述了调制盘的设计过程,采用单调制盘来缩小驾束制导仪的体积和重量。考虑到制导仪器实际工作的各种因素,设计了调制盘内、外码道的宽度,起止位置和5种频率值。给出了调制盘确定偏航信息的原理,表征导弹位置信息的调制系数和频率的计算方法。针对调制盘两场交接处的误码问题,提出了变角度设计方法,将各频率沿径向方向旋转45,从而保证了5 ms的场周期,提高了制导精度。

Abstract: The spatial encoding principle of the modulation disk in a laser-beam riding guided sighting instrument is introduced. The design procedure of the modulation disk is described, and a single disk is selected to reduce the volume and weight of the guided sighting instrument. By considering every influencing factor of guided sighting instrument, the width, start-stop positions of inner and outer code paths and five kinds of frequencies are designed. The principle of defining deviation information, modulation coefficient characterizing the position information of a missile and the method of computing frequency are given. To avoid error codes of two fields' alternation, the design method to change angles is presented to rotate every frequency pattern 45 along the radial of the modulation disk. Experiments show that the method ensures the field cycle of 5 ms, and improve the guided precision.
