With the development of the ImSyn™ processor by Essex Corporation, it is possible to perform high speed, high performance synthetic aperture radar (SAR) image reconstruction on inexpensive image processing workstations. The processor facilitates SAR phase history analysis and research in other frequency domain imaging techniques. During image reconstruction, it permits flexible interaction with the process steps so that autofocus and motion compensation algorithms can be readily implemented.
Like many imaging techniques in which the target is sensed in the Fourier domain, SAR sensors sample frequency space non-uniformly. Because the samples do not fall on a rectangular grid in frequency space, common algorithms such as the fast Fourier transform (FFT) cannot be utilized until compute-intensive interpolations have been performed. Because the ImSyn™ processor is designed to process arbitrarily sampled data without interpolation, it represents a major advance in image throughput and quality.
ImSyn production units started to ship in December 1996. A beta site partnership program is underway which forms a collaborative relationship with our first customers. Please click on the ImSyn Beta Sales button on the homepage.
