Research abstract
AN EFFICIENT ARCHITECTURE WILL BE DESIGNED FOR THE PHASING, EXCITATION, CONTROL, AND CALIBRATION OF A LARGE SPACE BASED ARRAY. IT IS PROBABLE THAT SIGNAL DISTRIBUTION WILL BE BY CLOSED OR OPEN OPTICAL PATHS. PHASING MAY BE BY DIRECT DIGITAL AT LOW FREQUENCIES, ACOUSTICAL LENSES AT MIDDLE FREQUENCIES, AND CONVENTIONAL PHASESHIFTERS AT HIGH FREQUENCEIS. RF EXCITATION DISTRIBUTION WILL BE BY CLOSED OR OPEN PATHS AT FREQUENCEIS LESS THAN 10 GIGAHERTZ. CONTROL DISTRIBUTION WILL BE BY DIGITAL MODULATED OPTICAL SIGNALS. CALIBRATION WILL BE INVESTIGATED. LEADING CALIBRATION CANDIDATES ARE LASER TRACKERS, LENGTH MODULATED ELEMENTS, AND FAR FIELD SOURCES.
