Abstract
A theoretical analysis has been done to estimate background clutter leakage noises due to vibrational motion in an AC-coupled mosaic sensor. The motion is separated into uniform drift-dominant and jitter-dominant cases. For the former case, a mathematical expression is obtained to give mean square clutter leakage in a summation form which includes the effects of background scene spatial variations, optical transfer function, footprint size, drift velocity and a smear function. The summation expression is simplified to obtain closed forms for equally spaced fill and spill samples and also for samplings at the end of a frame tine. In the jitter-dominant case, the leakage estimate is shown to depend upon both vibrational frequency and the statistics of the jitter motion.
