摘　　要：利用跟踪微分器开展捷联导引头视线角速率提取算法研究。首先描述了跟踪微分器提取捷联导引头视线角速率的数学机理,随后提出了一种利用旋转等效合力快速获取跟踪微分器频域特性的方法,并基于频域特性开展了两种典型跟踪微分器的参数设计与性能分析,最后基于以上的设计结果开展建模仿真与计算分析,验证跟踪微分器的视线角速率解耦效果。In this paper, the tracking differentiator is used to extract LOS angular rate of strapdown seeker. Firstly,the mathematical mechanism of extracting LOS angular rate of strapdown seeker by tracking differentiator is described.Then, a method of fast obtaining the frequency-domain characteristics of tracking differentiator by using the rotating equivalent force is proposed. Based on the frequency-domain characteristics, the parameter design and performance analysis of two typical tracking differentiators are carried out. Finally, based on the above design results, modeling simulation and calculation analysis are carried out to verify the LOS angular rate decoupling effect of tracking differentiator.
