摘要：

We present a statistical description of the centroid fluctuations of imaged targets under coherent illumination. We derive analytic expressions that take into account the illumination and imaging geometries. The fluctuations are shown to be insensitive to linear filtering and constitute a physical limitation to remote sensing devices making use of lasers.
