摘要/Abstract

摘要： 针对飞机姿态扰动和强烈震动条件下激光通信中的光轴稳定问题，研制了粗精复合跟踪机构，并对减振器安装结构形式进行了分析，完成了减振系统设计和伺服系统仿真。在此基础上开展了飞机姿态和振动特性测试，根据测试结果，绘制了振动试验曲线。进行室内仿真检测和外场飞行测试的试验结果表明，在大气信道条件下，粗跟踪吊舱跟踪精度优于23.97 μrad，精跟踪精度优于7.03 μrad. 对比实验室和外场测试环境的差异，可知大气干扰引起的光斑闪烁是导致跟踪精度下降的主要原因，为系统指标分配和吊舱跟瞄精度的提高提供了参考。

Abstract: For the optical axis stability problem of airborne laser communication, a coarse and fine tracking system is proposed. The installation structure of the shock absorber is analyzed. Avibration reduction system is designed, and the servo system is simulated. On this basis, the vibration and movement characteristics of the aircraft are measured. The measured results meet the laboratory simulation input. The simulation tests and the field tests of tracking accuracy are carried out. The reults show that, under the condition of atmospheric channel, the tracking accuracy of coarse tracking system is better than 23.97 μrad, and the tracking accuracy of fine tracking system is better than 7.03 μrad. The results are greater than the laboratory simulation test results, which provide a reference for the system index allocation and the improvement of pod accuracy.

Key words: apparatus and intruments technology, laser communication, airborne stabilized pod, tracking accuracy test, flight test
