ABSTRACT:
A method and apparatus for precisely determining the relative velocity of an interferometer and a scene being scanned. The apparatus uses a matched filter technique in which reference signals based on high and low relative velocity estimates are correlated with an incoming interferometer signal and controllably adjusted until the correlation is maximized. The controllably adjusted reference signals are then used to produce an extremely accurate and precise measurement of relative velocity.
