光电经纬仪多目标实时交会方法

Multiple Targets Real-time Intersection of Optic-electronic Theodolite

为实现实时计算多个目标飞行轨迹,并引导设备跟踪目标,根据目标运动特性和光电经纬仪跟踪测量的固有特性,设计了一种多目标实时交会方法,解决了同名目标点的排序和假目标轨迹剔除问题,最终得到正确的目标轨迹.试验证明,对于跟踪目标N≤3,通信周期50ms的光电经纬仪测量系统,利用该多目标实时交会算法处理测量数据,可实时、精确、稳定引导测量设备进行跟踪工作.

In order to achieve the real-time calculating about the flight trajectories of the multiple targets and guiding the equipment to track the targets,a real-time multi-target intersection method was proposed.Such method is based on the characteristic of target movement and the inherent characteristic of optic-electronic theodolite tracking measurement.This algorithm can achieve the goals of sorting homologous measurement data and eliminating the false target trajectory,and finally get the true target trajectory.The algorithm is applied to the optic-electronic theodolite measuring system which is under the condition of target N≤3and communication cycle being 50 ms.The experiment results show that the method can guide the measuring equipment to track accurately,stably and in real time.
