摘要
基于空间调频编码的原理,阐述了激光驾束制导武器系统的工作原理,研究了实现该系统的编码方式和调制技术。建立了偏离误差的数学模型,设计了一种新的调制盘的工作图案,该图案是相错90°的两条码道,每条码道是刻有一定规律的明暗相间的三排光栅图案组成。能以二维的坐标给出导弹的方位信息,且可线性地给出导弹偏离光轴中心的脱靶量。该调制编码设计已经过了室内及2公里的野外实验,实验结果表明:对导弹脱靶量的测量是可行的,各参数设计能满足制导精度要求,效果良好。
Based on the principle of space frequency - modulation, modes of space encoding and modulating technique are discussed. Then, the mathematic model to calculate the deviation is obtained, and operating principle for a kind of guidance weapon system is set forth . A new pattern of modulated disk is designed. The pattern is composed of two light pathes, which are crossed 90°, and each light path has three row of regular optical gatings. Azimuth information of target is given in 0rthogonal coordinate system and missdistance of deviation center is linearity.. The scheme has been tested in 2 kilometers outdoor, and the experimental results prove that: Measuring for the missdistance is feasible and all the performance parameters satisfy the demand.
