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 ...

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.

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.

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.

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

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.

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 ...

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 ...

Harmonic Synthetic Aperture Radar Processing
IEEE Geoscience and Remote Sensing Letters, 2015We review the basic concept of frequency-modulated continuous wave (FMCW) and describe how such a radar system can be used in a harmonic radar concept. It is argued that synthetic aperture radar (SAR) for FMCW harmonic radar can be implemented by carefully choosing the wavenumbers in the mixing part of the FMCW concept.
