Abstract

Essex has developed the ImSyn processor, a sophisticated hybrid of optics and electronics. ImSyn calculates a discrete Fourier transform. The current production ImSyn is optimized for synthetic aperture radar processing, but has been used to process MRI, acoustic tomography, and synthetic aperture microscope data. The key feature of the production ImSyn is the ability to calculate images from non- rectilinearly gridded data. This data cannot be transformed with the FFT algorithm without interpolation or regridding. An alternative version of ImSyn is being developed for correlation applications. The correlator will be optimized for speed in performing rectilinear transforms.
