捕获跟踪与瞄准系统的基本技术问题

The Basic Technologies of the Acquisition,Tracking and Pointing Systems

本文分析了光电捕获跟踪与瞄准系统的概念、技术要求及基本技术问题,并指出响应速度和跟踪精度是系统的关键。为实现快速捕获与高精度跟踪瞄准,必须提高光电探测器性能、改善结构设计并采用高精度控制技术等。本文对复合轴结构、视轴稳定技术、成象跟踪、前缋控制和滤波预测等作了详细的分析与讨论。本文还指出采用自适应光学技术的跟踪系统是很有前途的。

The concepts,requirements and basic technologies of the acquisition,tracking and pointing systems are analysed in the paper.The response speed and track- ing accuracy are keys of the system.Improvement of performances of photode- tector,design structure and applying control technologies with high accuracy are important for fast acquisition,precision tracking and pointing.Some technologies, for example,the combined axis,the stabilization of line of sight,the feedfor- ward control and filter prediction are discussed in detail.The tracking system with adaptive optical subsystem is very useful in the future.
