摘要
与非合作目标相对距离的精确测量是追踪器对其实施伴飞监视的关键技术之一。目前相对距离测量主要采用激光雷达作为测量敏感器,而国内的相关技术还不够成熟,难以满足任务需求。探讨一种新的相对距离的测量方法,追踪飞行器按特定方式进行一次或几次主动机动,根据机动过程中光学导引头测量的视线角序列,结合非线性滤波技术,对非合作目标相对距离进行精确估计测量。仿真结果表明,该方法可快速有效的精确测量非合作目标的相对距离,为监视伴飞任务提供技术支持。
Accurate measurement of relative distance is necessary for the surveillance and companion flying for noncooperative targets. Domestic Laser Radar technique is not competent enough for this requirement. A method for estimating relative distance for noncooperative targets was discussed. The relative distance was estimated by a nonlinear filter using Line-of-Sight Angle sequences during one or a series of several preplanned maneuvers of the tracing aircraft. Simulation results show that this method can support the surveillance and companion flying for noncooperative targets effectively by measuring the relative distance.
