Notes

Abstract:
This document presents a modular, extensible, framework for rendering images from synthetic aperture radar (SAR) data on an array of heterogeneous processor architectures, and applying change detection to that image output. Change detection output is fed back into our algorithm's scheduling engine, allowing the image formation process to proceed in non-uniform resolution. This allows time and energy constraints to be satisfied, while still ensuring that areas of high activity are imaged in high resolution, as required by the change detection output. Our design supports real-time reconstruction of a two-dimensional image from a matrix of echo pulses and their corresponding response values using Backprojection. Key to our design is the division of the backprojection problem into atoms, which decomposes backprojection along both it’s input and output data dimensions, and allows scheduling algorithms to explicitly minimize communication overhead through the deliberate assignment of atoms to processors.
