The TanDEM-X constellation is served by two X-band SAR satellites, which fly in close orbit formation acting as a large and flexible single-pass radar interferometer. This paper investigates the potentials for monitoring sea ice in the Bohai Sea with the unique constellation. Our results show that the coherence and interferometric phase of TanDEM-X data can be used to detect sea ice, and the radial...
Selecting discriminate features and constructing an appropriate classifier are two essential factors for ship classification in a synthetic aperture radar (SAR) image. Unfortunately, these two factors are rarely considered together by existing studies. We propose a joint feature and classifier selection method by integrating the classifier selection strategy into a wrapper feature selection framework...
A new time-frequency representation approach based on the generalized S-transform (GST) was developed to analysis synthetic aperture radar (SAR) images. At first, a SAR image is decomposed into one-dimensional (1-D) signals by choosing different scalable windows, rather than doing S-transform directly. Then, algorithm simulations and textural feature analysis are conducted using both basic S-transform...
Target detection and recognition is the ultimate aim in computer intelligence. Given an example of linear target, bridge over water in SAR image, the algorithm of denoise and segmentation is designed based on fuzzy theory, the detection of bridge edge is realized by minimum and Radon transform, and a measurement of judging parallel is proposed in this paper. In the process of designing algorithm,...
