摘　　要：T/R-R高频地波雷达可以对海面目标超视距探测,探测距离高达几百公里,因此由雷达量测量对目标定位应考虑地球曲率影响.本文分别给出了球面定位算法及其定位精度公式.应用加权最小二乘算法可实现目标精确定位.仿真分析了平面定位偏差、加权最小二乘球面定位GDOP.结果表明球面定位算法可消除定位偏差,加权最小二乘球面定位可提高目标定位精度.T/R-R high frequency surface wave radar（HFSWR） can detect over-the-horizon sea targets which are hundreds of miles away.The earth curve should be taken into consideration when determining target position using the measurement information obtained by HFSWR.We present sphere positioning algorithm to calculate target position and corresponding accuracy.Weighted least square（WLS） method is applied to sphere positioning algorithm to improve positioning accuracy.Computer simulations are leaded to analyze deviation of target position obtained by plain positioning algorithm.GDOP of sphere positioning algorithm using WLS method is also simulated.We conclude that sphere positioning algorithm can eliminate position deviation.Besides,sphere positioning algorithm using WLS method improves target positioning accuracy.
