摘　　要：为提高利用对流层散射信号超视距侦察定位响应速度,进一步降低计算误差,研究并提出了一种改进的测向方位面定位算法,分析了计算误差。仿真分析结论表明,该算法简单,具有计算误差小、反应速度快等特点,适合于工程应用。In order to improve the response speed of over-the-horizon reconnaissance and location based on tropospheric scattering signal and further reduce the calculation error, this paper studies and presents an improved azimuth location algorithm for direction finding, and analyzes the compu- tational error. The simulation analysis results show that the algorithm is simple and has small com- putational error 8a fast response,which is suitable for engineering application.
