The SAR Payload Design and Performance for the GF-3 Mission
Jili Sun,Weidong Yu,Yunkai Deng +2 more
TL;DR: The C-band multi-polarization Synthetic Aperture Radar sensor for the Gaofen-3 (GF-3) mission is described and an accurate antenna model is introduced for the pattern optimization and SAR performance calculation.
Journal ArticleDOI
A New CFAR Ship Detection Algorithm Based on 2-D Joint Log-Normal Distribution in SAR Images
TL;DR: Considering the ship target's gray intensity distribution and its shape difference compared to the clutter, a new algorithm is presented based on correlation that can reduce the false alarms caused by speckle and local background nonhomogeneity and the detection performance is much better.
Journal ArticleDOI
Generation and Transmission of OAM-Carrying Vortex Beams Using Circular Antenna Array
TL;DR: In this paper, a circular phased antenna array was used to generate OAM-carrying radio beams that possess ring-shaped intensities and helical phase fronts, and a communication system was proposed and validated using the superimposed OAM modes by using appropriate excitation settings.
Journal ArticleDOI
Processing the Azimuth-Variant Bistatic SAR Data by Using Monostatic Imaging Algorithms Based on Two-Dimensional Principle of Stationary Phase
Robert Wang,Yunkai Deng,Otmar Loffeld,Holger Nies,Ingo Walterscheid,Thomas Espeter,Jens Klare,Joachim H. G. Ender +7 more
TL;DR: A new bistatic point target reference spectrum is presented, derived by using the 2-D principle of stationary phase which is first applied in the synthetic aperture radar (SAR) community and contains two hyperbolic range-azimuth coupling terms and thus is very similar to the monostatic spectrum.
Journal ArticleDOI
SAR ATR based on displacement- and rotation-insensitive CNN
TL;DR: The results show that the classification accuracy is very low when the target’s displacement or rotation angle is different from the pre-assumed value in the training dataset, so a displacement- and rotation-insensitive deep CNN is trained by augmented dataset.
