Synthetic aperture radar interferometry
Inverse Problems, 1998Summary: Synthetic aperture radar (SAR) is a coherent active microwave imaging method. In remote sensing it is used for mapping the scattering properties of the Earth's surface in the respective wavelength domain. Many physical and geometric parameters of the imaged scene contribute to the grey value of a SAR image pixel.

Transionospheric Autofocus for Synthetic Aperture Radar
2023 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2023This paper presents an algorithm to mitigate the distortions caused by ionospheric turbulence on SAR space images. To quote the authors: ``In the current work, we propose a new optimization-based autofocus algorithm that helps correct the turbulence-induced distortions of spaceborne SAR images''.

Inverse Synthetic Aperture Radar Imaging Using a Fully Convolutional Neural Network
IEEE Geoscience and Remote Sensing Letters, 2020The traditional inverse synthetic aperture radar (ISAR) imaging uses the range-Doppler (RD) type of methods. The compressive sensing (CS)-based ISAR imaging is capable of obtaining good target images of high contrast and less sidelobe with much less ...

Principles Of Synthetic Aperture Radar
Surveys in Geophysics, 2000Synthetic Aperture Radar (SAR) is an active microwave imaging method. It operates independently of Sun illumination and cloud coverage. Current spaceborne systems use wavelengths of 3 to 25 cm and achieve resolutions of 10 to 50 m. The paper attempts to explain the basic SAR imaging principles using a minimum of mathematics.

An Universal Circular Synthetic Aperture Radar
IEEE Transactions on Geoscience and Remote Sensing, 2022This article presents an universal circular synthetic aperture radar (SAR) (UCSAR) by which the targets to be observed at any radial distance can be imaged, thus making SAR imaging possible in a more general scenario with a circular movement of the radar platform.

The previous discussions of this A.S.I. of target scattering and effects of the atmosphere upon microwave propagation are extended to the problem of imaging by synthetic aperture radar (SAR). The foundation for discussion of SAR system performance has been given by Corless [1].
