摘要
本文简单介绍了大处理角超宽带合成孔径雷达（ＵＷＢ－ＳＡＲ）波数域成像算法，研究了其中Ｓｔｏｌｔ插值的内容及其必要性，提出了几种插值方法来解决其中的插值问题。最后，利用所提出的几种插值方法进行仿真，得到了较好的聚焦效果，表明所提插值方法是有效的。
In this paper,the wavenumber domain algorithm for large processing angle UWB SAR imagery is briefly described.Then the content and necessities of Stolt Interpolation are studied.And some intpolating methods are presented to work for Stolt Interpolation.Lastly,with these methods,many emulations are made and good focusing results obtained.It is clear that all methods introduced are efficient.
