Abstract

The speckle size metric known as power-averaged speckle size (PASS), which is based on the integral of the power spectral density of the data, is insensitive to target asymmetry. PASS is defined as the inverse of the median frequency of the power spectral density of the reconstructed pupil. Implementation of the metric using simulated data from different targets under a variety of imaging conditions illustrates the impact of the environment. In this paper, we deconvolve the imaging environment using power spectral density of the detected speckle in the error function. Different targets are simulated in the presence of a variety of imaging situations as well as noise and we compare the resultant deconvolved images with undistorted images as well as with the unimproved ones.
