| 摘 要： | 为尽量简化多测速雷达定轨系统的气象测量，探讨了采用Hopfield对流层折射指数模型代替探空气象测量的适用性。主要分析了采用Hopfield模型与采用实际探空测量数据的折射误差修正量差别，目标轨迹误差对修正量的影响，以及气象参数对修正量的影响。

| Abstract: | This paper discusses the applicability of the replacement of meteorological data surveying by sounding balloon with Hopfield tropospheric refraction index model to simplify meteorological data survey for multi velocity measuring radar system. It mainly analyzes the difference of refractive correction between adopting Hopfield model and using actual meteorological data surveying by sounding balloon, and the influence on refractive correction caused by the target trajectory errors and meteorological parameter errors. |
