| 摘 要： | 传统的双雷达地面目标定位算法因测量数据本身固有的误差和量测噪声,使得基于非线性估计定位算法的定位精度不高。本文研究了一种新的双雷达地面目标定位算法,该算法将已知雷达探测数据以几何方式加以表示,通过几何解析对地面目标进行定位。此外,还详细分析了各种因素在不同情况下对定位精度的影响。所研究的算法具有计算量小、远距离定位精度高等优点。最后,通过仿真验证了该算法能够提高远距离定位的定位精度。

| Abstract: | Classical location algorithms for ground target using twin-radar system are nonlinear estimation problems. But the inherent error of measurement data results in low positioning accuracy of location algorithm based on nonlinear estimation.In this paper, a new location algorithm is developed,which transforms measurement data into geometric figures and locates targets using geometry analytic method.All factors that can effects on positioning accuracy in all kinds of cases are analyzed.The algorithm has advantages of small calculation,high long-distance positioning accuracy and so on..Finally,the simulation results are given to illustrate that the algorithm has obviously good performance on improving positioning accuracy. |
