【摘要】 在军事实战中单点被动定位系统往往与主动定位系统交替使用,所以,具有一定初始条件(初始距离、初始速度)的单点被动定位系统所使用的算法研究十分重要。文中在三维空间运动几何模型的基础上,结合目标和观测器各自的速度约束条件,提出了运动目标的三维空间三坐标角度测量单点被动定位算法的模型。建立了该模型下单点被动定位方程,讨论了定位方程解存在的条件,得出方程具有双解的结论。结合高速运动目标的航迹在任意相邻3个观测点上共线的假设,确定了定位方程的唯一解。最后,利用计算机仿真了三坐标角度测量单点被动定位的算法。多种目标航迹的仿真结果表明,该算法对来袭目标的各种航迹有效,定位相对误差优于±2%。更多还原

【Abstract】 In practical war case a monocular passive location system usually works as a substitute of an active location system,so it is every important for research on algorithm for passive location system with some initial condition(initial distance and velocity).Based on the three-dimension space movement geometrical model,together with the velocity restraint conditions of target and observer respectively,a model is proposed for algorithm for three-dimension space three-coordinate angle measurement monocular passive location to moving target.The location equations under this model is obtained,the solution existence requirement is discussed,a conclusion is drawn that there may exist two solutions.Consequently,the only solution is achieved upon the supposition that each adjacent three dots in the track are on a line for a target with high velocity.At last,the relevant stimulating system is build,with which location to several track is done.It has shown by computer simulation that the new algorithm is valid for all kind intruding target tracks,and the relative error is less than ±2%.更多还原
