Abstract:

The coherence factor (CF), defined as the ratio of coherent power to incoherent power received by an array of sensors for a given point in an image scene, is applied to through-wall image processing. It is shown that CF filtering reduces clutter and increases clarity and uniformity in the image by suppressing the low-coherence features. It is also shown that through-wall propagation degrades the CF, thereby enabling its use as a quantitative metric for autofocus and image correction algorithms.
