从降低高频单站定位误差、提高系统整体性能角度出发，系统性地分析了高频单站定位误差源——电离层虚高、测量仰角和方位角——对定位误差影响的规律。基于误差特性分析结果，提出了优化定位精度的构想：一是通过选择合理的电离层模型r并基于探测数据进行实时修正来提高电离层虚高准确度；二是通过选择优质测向体制和天线场地、研究基于电离层斜向探测等技术的测向校正方法来提高测向准确度；三是应用迭代算法用以克服方法近似所带来的误差。通过方法可行性，论证了优化构想和电离层斜向探测技术对提高高频单站定位精度的重要意义。

With a view to reduce error and increase performance of HF single site location （SSL） system, the location error impacted by the HF SSL error sources, including ionosphere virtual high, measuring elevation and azimuth, is systematically analyzed. The idea of optimall location accuracy is presented. First it is im- proved the accuracy of the ionospheric virtual height by choosing a reasonable model of the ionosphere and the real-time amendment of the sound-based data. Next, the accuracy of direction finding is promoted by choosing the high-quality SYstem and high-quality antenna site and using the direction finding calibration method based on the ionospheric oblique sounding technique. Then, the iterative algorithm is used to overcome the error caused by approximate calculation. Finally, the signific;int of both the accuracy optimizing idea and the ionospheric oblique sounding technique in improving the HF SSL accuracy are. demonstrated.
