三维移动目标无源定位算法
|
摘要
无源定位已经成为雷达对抗中一项相当重要、不可或缺的技术。针对常态侦察时三维移动目标的无源定位问题,考虑了基于到达方位信息的代数几何概率定位方法,并给出了每一时刻目标位置误差随时间变化的关系,最后通过数值模拟展示了所研究定位方法的精度。该算法基于运动学原理,充分利用了辐射源信号测量值的时空变化量信息,定位收敛速度快而且非常稳定,具有很强的实用性。以期在实际应用中对近空间或邻近空间中高速移动目标进行三维快速定位,更好地提供无源侦察中移动目标的方位情报信息。
Passive positioning has become a very important and indispensable technology in radar confrontation.Aiming at the passive location of 3D moving targets in normal reconnaissance,an algebraic geometric probabilistic positioning method based on arrival position information is considered,and the relationship between target position error and time at each moment.Finally,numerical simulations show the accuracy of the proposed method.Based on the kinematics principle,the algorithm makes full use of the spatio-temporal change information of the measured value of radiation source signal,so that the positioning convergence speed is fast and very stable.This method could help three-dimensional rapid positioning of high-speed moving objects in near space and provide position information of moving targets in passive reconnaissance.
