Abstract
We demonstrate experimentally the ability to shape the point spread function of a distributed-aperture millimeter-wave imaging system by modifying its aperture phase. We consider distributions on a regular hexagonal array and a nonredundant array. We also show how to exploit this capability to perform low-resolution analog image processing. A preliminary investigation of system performance reveals nonuniformity in amplitude response across the array is a major contributor to deviations from predicted point spread functions (PSFs).
