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].

High angular resolution radar imagery can be obtained using conventional non-coherent radar systems by employing a large antenna or operating at a short wavelength. Airborne platforms, however, impose severe physical limitations on the size of the antenna which can be used and still maintain acceptable flight characteristics of the aircraft. The use of

Some of the most striking images of the earth’s surface have been made from aircraft in level flight using radar in a sophisticated modality. The foliage of trees is stripped away and the ridges and gullies of the hard surface are shown in stark relief.

Synthetic Aperture Radar Processing with GPGPU
IEEE Signal Processing Magazine, 2010Synthetic aperture radar (SAR) processing is a complex task that involves advanced signal processing techniques and intense computational effort. While the first issue has now reached a mature stage, the question of how to produce accurately focused images in real time, without mainframe facilities, is still under debate.

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 ...

Synthetic aperture radar image formation
International Conference on Acoustics, Speech, and Signal Processing, 2002The implementation of a subaperture technique for image formation in a synthetic aperture radar system (SAR) is presented. Coherent subaperture techniques for SAR image formation involved partitioning the data (in the time domain) into subapertures. The data in each subaperture are used to form low-resolution images which are combined coherently to ...
