Abstract
A system and method for a bistatic coherent LIDAR system with lasers locked to a reference. Utilizing atomic absorption lines to lock the frequency for the bistatic system provides an absolute reference, as each of the lasers in the bistatic system would have the same frequency to within the linewidth of the frequency reference. Each laser may also be additionally locked to an optical cavity for increased frequency stability. Not only does such a system provide essentially an infinite aperture, it also reduces laser power requirements because the detector platforms could be much closer to the target than the platform that contains the laser.
