摘　　要：光电火控系统主要由光电跟踪系统、火控计算机、火炮随动系统组成,光电跟踪系统视频取差器的滞后特性以及火炮随动系统的不平稳性,直接制约着光电火控系统精确跟踪并打击目标的性能。针对上述问题,介绍了非线性跟踪微分器的原理,利用其滤波特性和微分信号提取特性,创造性地提出将其应用于光电火控系统中。仿真和工程试验证明,采用非线性跟踪微分器的系统,在跟踪精度上有明显的提升。Photoelectric fire control system is mainly composed of photoelectric tracking system,fire control computer and servo system,the delay of tracking deviate for photoelectric tracking system and the motion instability of servo system,can affect tracking and shooting accuracy in photoelectric fire control system. To solve questions above,the tracking-differentiator’s principle is given firstly,and then,its filter characteristics and differential signal extraction are applied in photoelectric fire control system. It has been confirmed that the photoelectric fire control system using tracking differentiator is more accurate in tracing.
