摘　　要：对剩余静校正的Ｒａｄｏｎ变换方法作了简要介绍．当用二维可积函数统一定义剩余静校正量项、构造项和剩余动校正量项的各项分布时．可以把广义剩余静校正方程同Ｒａｄｏｎ变换联系起来，因而应用Ｒａｄｏｎ逆变换就可以反演出剩余位静正量项．用Ｒａｄｏｎ变换方法对几组理论数据进行处理，并与广义线性反演剩余静校正方法比较，结果表明应用Ｒａｄｏｎ变换在一般的剩余静校正问题中可以得到精度更高的剩余静校正量．The generality of this method is briefly introduced in this paper. The general residual statics equation can be related to the Radon transform by a 2 - D integrable function to define the distributions of the residual statics terms, the structure term and the residual NMO term all together. Therefore, the residual statics terms can be found by applying the inverse Radon tromsform. A few sets of theoretic data are processed by the Radon transform method and the results are compared with those calculated by the general linear inversion method. The comparison between the two methods shows that higher precision can be reached by the Radon transform processing.
