In high-sensitivity, deepspace surveillance missions, detection of point-source target satellites must be accomplished amid a background of thousands of stars. These stars must be removed from the data stream to permit target detection and to accommodate the data stream to the capacity of the downlink. Two different star elimination techniques, color elimination and moving target indicator (MTI) are analyzed and compared. It is shown that neither of two color discrimination schemes is adequate to meet the data downlink capacity goal. Star leakage is reduced by two orders of magnitude using MTI rather than color discrimination. Thus, the downlink data rate is reduced dramatically along with the probability of false target occurrence. Therefore, the MTI technique is a promising scheme for rejecting inertially stationary objects.
