摘　　要：本文回顾了大气折射引起的电波传播射线弯曲特性,通过采用我国大气折射率的统计模型和高精度的电波折射误差修正方法—射线描迹法,进行目标定位误差分析,针对中近程雷达的应用背景,计算了一些可为高精度中近程雷达的俯仰测角修正提供参考的数据。Bending characteristics of electric wave propagation ray caused by atmospheric refraction is reviewed. Target location error is analyzed by using statistical model of refraction rate in our country and high accuracy electric wave refraction correction method-ray tracing method. Aiming at application background of medium/short range radar, some data which can be used as reference for correcting angle measurement error in elevation of high precision medium/short range radar is calculated.
