A new method to recognize ship target in SAR imagery using an Active Appearance Model (AAM) is proposed in this paper. The AAM can describe both shape and grey-level appearance of target which can present the SAR target more accurately.The application of AAM in SAR targets recognition was discussed in details. And the effectiveness of the method was demonstrated through the ship target classifi...

Future high resolution multi-aperture SAR satellites entail high potential for large-area traffic monitoring from space. While many approaches for detecting across-track moving vehicles in SAR images have already been published within the recent years, the detection of objects moving in along-track is still an issue to be solved. This paper deals with the detection of vehicles, mainly moving in...

Systemic acquired resistance (SAR) is an inducible immune response that depends on ENHANCED DISEASE SUSCEPTIBILITY1 (EDS1). Here, we show that Arabidopsis (Arabidopsis thaliana) EDS1 is required for both SAR signal generation in primary infected leaves and SAR signal perception in systemic uninfected tissues. In contrast to SAR signal generation, local resistance remains intact in eds1 mutant p...

in this paper, a block-based method in wavelet domain for sar image coding is presented based on the ezbc algorithm. to better preserve edges and textural structure in sar images, instead of using traditional dyadic wavelet transform, a packet wavelet is employed. to improve the efficiency of the ezbc algorithm for sar image coding, a modified version of this algorithm, is proposed. this modifi...

The asynchronous transfer mode (ATM) adaptation layer type 1 (AAL1) segmentation and reassembly (SAR) are designed and implemented by the field programmable gate array (FPGA). The SAR header is generated and processed in the FPGA and the SAR payload is stored in an external first-in–firstout (FIFO) device. A method to recover the source clock, called synchronous residual time stamp (SRTS), is i...

In this paper we propose a new statistical model for SAR images. According to this model, the SAR image amplitude follows a product of Rayleigh and Bessel functions. We derive the maximum likelihood feature detector for extracting terrain features from Synthetic Aperture Radar (SAR) images. The terrain features are classified as ridges and ravines according to their statistical properties and s...

SAR VHDL program writes in Xilinx ...

The author introduces the status of the Japan Aerospace Exploration Agency’s synthetic aperture radar (SAR) programmes and their scientific returns from the last 20 years of activity. The Earth observation programme was started using active microwave sensors in the early 1990s. Spaceborne SAR aboard Japanese Earth Resource’s Satellite-1 (JERS-1) was the pathfinder, and airborne polarimetric and...
