摘　　要：从Haselgrove射线方程出发,利用短波射线追踪技术,计算了天波超视距雷达在有无地磁场条件下的定位误差,分析了地磁场对雷达目标定位的影响。仿真结果表明,在超视距雷达定位精度要求较高的工程应用下忽略地磁场的影响是不合适的。该文的工作可为雷达波的电离层修正方面提供参考。In this paper,the ground target location of over the horizon radar（OTHR） was discussed in detail based the ray tracing technique and the Hlselgrove equation. The effect of geomagnetic field on the location of OTHR was presented.The simulation results show that it is not proper in the application requiring high location accurracy of OTHR without regard tothe geomagnetic field. The efforts of the paper can be used as reference in respects of the ionosphere correction for radar wave.
