合成孔径雷达的空间傅里叶分解成象
SPATIAL FOURIER DECOMPOSITION METHOD FOR SAR IMAGING
-
摘要: 空间傅里叶分解法是一种新的合成孔径雷达(SAR)成象方法。这种方法考虑到了波前的球面特性,所以即使在近场条件下,也不会像传统方法那样由于采用了平面波近似而使图象畸变。本文提出了一种空间傅里叶分解法的实现算法。对计算机模拟数据的成象结果证明了这种算法的的有效性。Abstract: The spatial Fourier decomposition method is a new method for the SAR imaging. It incorporates the spherical nature of the radar s radiation pattern and so the image would not distort even at near field. This paper presents an algorithm for the spatial Fourier decomposition method. The imaging results of simulated targets prove it is effective.
