Multi-aperture coherent imaging

Aperture synthesis offers the potential for high resolution images in a relatively compact system. We describe our multiaperture IMAGE testbed which uses coherent detection to measure the complex field in spatially separated apertures. We describe a post-detection optimization algorithm which is used to synthesize a composite image whose angular resolution exceeds that of a single aperture. We present experimental results in which we image extended targets at a simulated range using a compact range developed for this purpose.
