合成孔徑雷達(dá)的空間傅里葉分解成象
SPATIAL FOURIER DECOMPOSITION METHOD FOR SAR IMAGING
-
摘要: 空間傅里葉分解法是一種新的合成孔徑雷達(dá)(SAR)成象方法。這種方法考慮到了波前的球面特性,所以即使在近場(chǎng)條件下,也不會(huì)像傳統(tǒng)方法那樣由于采用了平面波近似而使圖象畸變。本文提出了一種空間傅里葉分解法的實(shí)現(xiàn)算法。對(duì)計(jì)算機(jī)模擬數(shù)據(jù)的成象結(jié)果證明了這種算法的的有效性。

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. -
