SAR images updated

open access: yesEos, Transactions American Geophysical Union, 1984
A new camera system using lasers and charge‐coupled devices and which can obtain data by radar at any time or under any weather conditions has been designed by the California Institute of Technology as part of a NASA continuing program. The system is intended to improve the imaging functions of synthetic operative radar (SAR) units. SAR units have been

Extended Subaperture Imaging Method for Airborne Low Frequency Ultrawideband SAR Data

open access: yesSensors, 2019
The subaperture processing is one of the essential strategies for low frequency ultrawideband synthetic aperture radar (LF UWB SAR) imaging, especially for the real-time LF UWB SAR imaging because it can improve the parallelization of the imaging ...

Sparse signal representation for complex-valued imaging [PDF]

open access: yes, 2009
We propose a sparse signal representation-based method for complex-valued imaging. Many coherent imaging systems such as synthetic aperture radar (SAR) have an inherent random phase, complex-valued nature.

On the remote sensing of oceanic and atmospheric convection in the Greenland Sea by synthetic aperture radar

open access: yes, 2004
In this paper we discuss characteristic properties of radar signatures of oceanic and atmospheric convection features in the Greenland Sea. If the water surface is clean (no surface films or ice coverage), oceanic and atmospheric features can become ...
