分析美国海军空间监视系统（也称电磁篱笆系统）在探测和定位临近空间目标的局限性，即对临近空间目标定位存在精度低和低空覆盖不够的问题。首先提出了增加大圆平面内接收站来覆盖临近空间，同时增加圆外站提高目标定位精度的方法。然后针对该体制直接采用最小二乘方法存在的问题，给出了电磁篱笆系统对临近空间目标的定位理论和具体实现算法。最后通过计算机仿真验证了提出的系统优化布站和定位方法的有效性，这些结论可为我国将要建设类似系统提供理论基础和指导。

This paper analyzes the limitations of the United States navy space surveillance system (NAVSPASUR,also known as electromagnetic fence system)in detecting and locating targets in near space, namely low positioning accuracy and insufficient low-altitude coverage.Firstly,we may increase radar receiv-ing stations in and outside the circle plane to cover near space and improve target positioning accuracy.More-over,the near space target orientation theory and realization algorithm is proposed based on analysis of the least square method.Finally,computer simulation results demonstrate validity of the proposed system opti-mization and target orientation method.These conclusions can provide the theoretical basis and guidance for building a similar system.
