In order to improve the accuracy of synthetic aperture radar images target recognition, we have proposed a new algorithm of SAR target recognition based on advance Deep Learning neural network. The traditional radar recognition algorithm has many disadvantages, In order to improve the accuracy of synthetic aperture radar images target recognition, the author have proposed a new algorithm of SAR...

This paper describes the C-band multi-polarization Synthetic Aperture Radar (SAR) sensor for the Gaofen-3 (GF-3) mission. Based on the requirement analysis, the design of working modes and SAR payload are given. An accurate antenna model is introduced for the pattern optimization and SAR performance calculation. The paper concludes with an overview of predicted performance which was verified by...

The High-Resolution Wide-Swath (HRWS) Synthetic Aperture Radar (SAR) system, promoted by EADS Astrium GmbH, has been object in the last years of intensive studies for his capability to overcome the conflict between azimuth resolution and swath width of conventional SAR. The original choice of a bistatic solution for the system architecture has been recently reconsidered and is currently oriente...

Motion compensation is an important part of SAR processing for high resolution air borne imaging sensors. The non ideal motion of the platform carrying radar, results in degraded image quality. This paper concerns the analysis and compensation of trajectory deviations in airborne Synthetic Aperture Radar (SAR) systems. Analysis of the received data spectrum is carried out with respect to the sy...

The sequence of echoes detected by an active Synthetic Aperture Sonar (SAS) is coherently added in an appropriate way to produce an image with greatly enhanced resolution in the azimuth, or along-track direction when compared with an image obtained from a standard Side Looking Sonar (SLS). The SAS processing originates from the Synthetic Aperture Radar (SAR) concept. A complete introduction to ...

Synthetic aperture radar (SAR) is a general method for generating high-resolution radar maps from low-resolution aperture data which is based on using the relative motion between the radar antenna and the imaged scene. Originally conceived in the early 1950s [1], it is extensively used to image objects on the surface of the Earth and the planets [2]. A synthetic aperture is formed using electro...

Introduction Outcomes attributable to the research funded through the 2005 NCPPT grant can be summarized as follows: 1) Protocols for the detection of archaeological sites through the analysis of commercially available synthetic aperture radar (SAR) and multispectral images. Previously existing protocols for site detection through image analysis had utilized images generated from synthetic aper...

We consider Synthetic Aperture Radar (SAR) image formation in the situation when the propagation medium is random and dispersive. The propagation model is the Klein-Gordon equation with a random index of refraction and a random dispersive term. We show via a multiscale analysis how the medium heterogeneities and the dispersion affect the image. In fact, in the situation with a strong source chi...
