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].

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.

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 ...

IEEE Transactions on Aerospace and Electronic Systems, 1967
The general theory of side-looking synthetic aperture radar systems is developed. A simple circuit-theory model is developed; the geometry of the system determines the nature of the prefilter and the receiver (or processor) is the postfilter. The complex distributed reflectivity density appears as the input, and receiver noise is first considered as ...

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

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).

The Capella Synthetic Aperture Radar Constellation
IEEE International Geoscience and Remote Sensing Symposium, 2018The Capella constellation will consist of 36 agile synthetic aperture radars. Each radar will operate at an altitude of around 500 km in an approximately 90-minute polar orbit, providing average imaging revisit times of less than one hour.
