Abstract

Infrared search and track systems are important to the Navy as early warning devices to detect fast moving sea-skimming threats. Sensors must be able to analyze severely distorted images since the propagation medium consists of long horizontal paths that are near the ocean surface. The thermodynamics of this configuration foster the formation of gradients in the refractivity, which in turn can create striking and puzzling anomalies in the perceived image. An accurate simulation of the propagation characteristics of signals is crucial to help elucidate possible errors. We describe work to develop simple topological methods to understand propagation distortions in the marine and coastal environment.
