Abstract
- The unsteadiness of the low altitude platforms leads to uneven light and shade in the azimuth of synthetic aperture radar (SAR) images. The traditional method for the azimuth intensity adjusting of SAR images has two important disadvantages. The first is its discontinuity of the normalization factor, and the second is its inapplicability on regions with broken terra of very weak or very strong back scatterer. This paper is focused on cutting down the discontinuity of the normalization factor and reducing the affection of the broken terra on the normalization factor. A new method is proposed in the adjustment of the intensity variance in the azimuth of SAR images by the image data in combination with the cross roll angle of platforms. The experiments and results show its good availability and robustness of the new method.
