摘　　要：为了解Curvelet变换在位场数据去噪处理中的效果,从Curvelet变换的原理着手,通过对多矩形棱柱体模型进行Curvelet变换去噪和普遍应用的小波阈值去噪试验对比,验证了Curvelet变换去噪的有效性问题。将其应用于实测位场数据的处理中,取得了较好的效果。理论和实测数据的处理结果都表明,Curvelet变换在位场数据的去噪处理中是可行有效的。In order to understand the effect of Curvelet transform denoising in potential field data processing,the study started from the principle of Curvelet transform,through contrasting the experiment between Curvelet transform denoising and wavelet threshold denoising used in general for the multiple rectangular prism model,the validity of the Curvelet transform denoising was verified.It is applied in the measurement of potential field data processing,and the good results have been achieved.Theory and the measured data processing results show that the Curvelet transform denoising is feasible and effective in potential field data processing.
