Current challenges in atmospheric propagation research

摘要

We present an analysis of atmospheric propagation effects on current and proposed imaging systems. Effects such as extinction, resolution, beam spreading, anisotropy, and heterodyne efficiency are discussed. We also discuss a new DARPA program that will use atmospheric turbulence to an advantage to achieve super-resolution imaging. This super-resolution imaging phenomenon exploits a micro-lensing effect caused by atmospheric turbulence through use of a fast camera and signal processing to achieve better-than-diffraction limited resolution.
