SAR image is hard to be interpreted by users compared with optical remote sensing image. And current automatic SAR image interpretation cannot meet the requirement of practical application. In order to overcome this problem to some extent, this article presents a new SAR image representation method called “SAR image re-imaging”. This second imaging SAR image is composed from the underlying information...
Flood is one of the most common and expensive natural disaster. Rapid and efficient procedure to accurately detect the flood-inundated area irrespective of weather conditions will help the monitoring and rescuing during the seasonal flooding period. In this paper, a procedure is proposed to obtain the flood mapping using multi-temporal TerraSAR-X data. And a comparative experiment is design to test...
With the development of synthetic aperture radar (SAR) in recent years, the explosion of SAR images has urged people to find efficient means for searching and organizing mass amounts of images. In this paper, we propose an approach to content-based retrieval of SAR images, which contains feature selection and relevance feedback. In the process of retrieval, a low-dimensional feature subset is selected...
This paper presents an accelerating Nonuniform Fast Fourier Transform (NUFFT) algorithm for imaging reconstruction of two-dimensional synthetic aperture radiometer. This algorithm relies on a mixture of the fast Gaussian gridding algorithm and the judicious use of the FFT on an oversampled grid. It is not limited for an equal spaced visibility function sampling, and has the advantage in storage compared...
Synthetic Aperture Radar (SAR) image due to its special imaging method has many different characters from optical image. In this paper, a objective image quality evaluation system is proposed with a set of parameters and relevant measurements that mainly based on SAR image itself. And this evaluation system is supposed to be used by both satellite-borne and airborne SAR system.
