Abstract

Space-variant blur occurs when imaging through volume turbulence over sufficiently large fields of view, and it is particularly severe in horizontal-path imaging and slant-path (air- to-ground or ground-to-air) geometries. We report on pre and post-detection correction methods based on the method of Phase-Diverse-Speckle (PDS), and demonstrate its potential for dramatic improvement via simulation results.
