摘　　要：在系统调研Radon变换及其各种改进方法、应用效果的基础上,对目前Radon变换的研究成果进行了总结。首先,详细介绍了Radon变换基本原理及适用性,重点介绍了在Radon变换中采用稀疏正则化约束提高分辨率、在受限模型空间中求解提高计算效率的一些具体应用与改进;其次对Radon变换在地震矢量数据处理中的应用进行了概要介绍。调研发现Radon变换在地震矢量场处理中的应用仍处于探索阶段,如何获得最佳的处理效果并保持其矢量场特性是Radon变换应用的发展方向,针对多分量地震数据,研发或改进现有的Radon变换方法使其适用于多分量矢量地震数据的处理将是以后该领域攻关的重点方向之一。Through the extensive investigation of Radon transform with its various improvement and application effects,current research results on Radon transform are summarized. On the basis of introducing the basic principles and applicability of various improved Radon transform methods in detail,this paper focuses on the introduction of using sparse regularization constraints in Radon transform to improve the resolution, and of deriving solution in the restricted model space to improve the iteration efficiency for massive seismic data.Moreover, this paper demonstrates that, the application of Radon transform in seismic vector field pro-cessing is still in the experimental stagehand that its development trend is to obtain satisfactory processing effects as well as to keep the vector characteristics.Moreover,there is an urgent need to design and improve Radon transform methods for multi-component seismic data processing in the immediate future.
