摘　　要：设计了单站光电雷达三维姿态测量系统,讨论了将该测量系统用于飞行目标三维姿态测量的可行性,研究了用该系统测量飞行姿态的原理、算法和误差项。依据选取的三维姿态解算算法确定了系统的关键技术指标,计算了系统对模拟目标的作用距离,并分析其三维姿态测量精度。分析结果表明,系统对模拟目标的作用距离不小于60 km,实时三维姿态测量总误差不大于120′。利用外场现有仪器的校飞试验进行了单站三维姿态解算实验,结果表明,利用单站光电雷达一体化测量系统来测量飞行目标的三维姿态信息方法切实可行,不但可提高仪器测晨的实时精度,而且可消除传统交汇测量法对布站的限制,提高了仪器使用效率。A single opto-electrical and radar integration system was designed and the feasibility to apply the system to measurement of three dimensional attitudes of flying targets was discussed.Then,the principles,algorithms and measuring errors of the system were researched. According to three-dimensional attitude computer methods,the system＇s key technical indicators were determined,and the effective distance and the attitude measurement accuracy of the system for a simulated target was analyzed.The results show that the effective distance to the simulated target distance is more than 60 km,and the real-time three-dimensional attitude measurement accuracy is less than 120′.By use of the exiting device,a single-station measurement experiment to the real-time three-dimensional attitude of the target was performed and the results show it is feasible to measure the three-dimensional attitudes of targets by single opto-electrical and radar integration instruments,which not only can improve measuring accuracy and working efficiency and also can eliminate the restriction for measuring instrument distribution.
