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''.

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.

Coprime synthetic aperture radars
2017 IEEE 3rd International Forum on Research and Technologies for Society and Industry (RTSI), 2017In this paper we present a comprehensive discussion regarding the application to Synthetic Aperture Radar of coprime array concepts. The proposed coprime SAR configurations, which we name CopSAR and OrthoCopSAR depending on the used waveforms, can be used to reduce the amount of data to be stored and processed and to increase the range swath, in case ...

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.

So far, most of our discussion has concerned RAR, in which the antenna is a physical object that first emits, then collects the radiation. We now turn our attention to the case in which the antenna moves to cover a synthetic aperture (LSA), thus producing SAR.

We describe the design and implementation of a novel SIMD data-parallel algorithm for real time SAR quick-look image generation using the Cell Broadband Engine as found in the consumer Playstation 3 gaming console. Our implementation of this chain on the CELL system processes 1 frame of image data, reading a 1024x3072 pixel of (simulated) RAW ...

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].

A short introduction to the background and theory of synthetic aperture radar (SAR) imaging is given. Some of the key issues in SAR design are discussed and possible future developments involving SAR operation with phased arrays are suggested.

Radar is an active microwave remote sensing system, first developed during the Second World War with the purpose of evaluating distances between targets (aircrafts, ships, etc.) and the antenna used to send and receive an Electromagnetic (EM) pulse (Woodhouse 2006; Brown 1999).
