某型号瞄准制导仪中调制盘图案的设计

基于旋转调频调制盘的定位原理,研究了某型号瞄准制导仪中调制盘图案的设计特点。该调制盘的设计具有调制盘的转动中心与光学系统的光轴不同心,连续线性反映目标的偏离量,以及以直角坐标方式给出目标的方位信息等特点。设计了该调制盘的外、内调制光路的调频图案。外、内调制光路上的图案分别刻饰有三条光路,它们各自对应着6个不同的频率区域。给出了该调制盘确定偏离信息的原理和频率的计算方法。该调制盘可以线性地给出偏离中心的误差信息。

Design of patterns of modulation disk in a certain modal of guided sight instrument

Based on positioning principle of rotating frequency-modulated disk, designing characteristics of patterns for some-model guided sight instrument are studied. The design characteristics are that center of the disk is not on optical axis, deviation of target is linear and continuous and azimuth information of target is given in orthogonal coordinate system. Detailed design of frequency-modulated pattern in inner- and outer-optical path of the disk is given. The patterns in outer- and inner-optical path are three optical path respectively which gives six different frequencies respectively. The principle of deviation information and method of computing frequency is given. Error information of deviated center is linearity.
