Laboratory targets have been imaged by a multi-sub-aperture, coherent receiver technique in which a common local oscillator illuminates the sub-aperture array to preserve both phase and intensity information. The target, receiver and range dimensions were chosen such that each sub-aperture was smaller than the speckle size. Various targets were illuminated by microsecond pulses from an e-beam pumped XeF power amplifier, which was seeded by a coherent ultraviolet beam generated with a frequency doubled visible dye laser. Data is presented showing comparisons between the coherent multi-sub-aperture approach and conventional, full aperture photography of the same target(s).
