摘要
在电波折射误差修正中,对于不同的精度要求应采用不同的方法。目前最常用的是大气球面分层法,这种方法是在大气水平均匀的假设条件下得到的,因此对于任意大气层用此方法时,除水平不均匀性引起的误差外,公式本身也存在一定的误差。利用在某山区大气探测数据,针对三站雷达测量系统分别用任意大气层和大气球面分层进行了电波折射误差计算,得到了大气球面分层法的公式误差。
We adopt differ method for corresponding differ accuracy in radiowave refractive errors correction. Atmospheric sphere sublayer method is used now. We derive the method from on condition that homosphere ,so the method is adopted for arbitrary atmosphere ,the formulas have certain error apart from no homosphere bring about error. Radiowave refractive errors are calculated by atmospheric profile of a mountainous area using arbitrary atmosphere method and atmospheric sphere sublayer method for three radar measure system,the formula errors method and atmospheric sphere sublayer method for three radar measure system,the formula errors of atmospheric sphere sublayer sublayer method are gived.
