| 摘 要： | 大气折射引起的雷达定位误差是限制雷达精度进一步提高的关键因素之一.针对目前只给出雷达测量参数的折射误差,不能明显给出实际应用中所需要的目标位置偏移误差现状.通过采用我国大气折射率的统计模型和目前公认的高精度的电波折射误差修正方法一射线描迹法,对大气折射引起的雷达定位误差进行了目标位置偏离的计算和拟合,建立了大气折射引起雷达测量目标的位置偏移误差模型,从而为雷达实际使用和精度评估奠定基础.

| Abstract: | The radar locating error caused by atmosphere refraction is one of the key factors that limit the further improvement of radar accuracy.At present,only the refraction error of the radar measuring parameter is presented,the deviation error of target position which is needed in practice can not be given. To solve the problem,we adopted ray marking method,a high-precision method for correcting radio wave refraction error and also the statistical model of atmospheric refraction in our country,to calculate and f... |
