Conference Proceedings on Atmospheric Propagation in the UV, Visible, IR and MM-Wave Region and Related Systems Aspects Held in Copenhagen, Denmark on 9- 13th October 1989
Abstract
Atmospheric propagation of electromagnetic waves at frequencies above 30 GHz, i.e. millimetre (MM) waves and infra-red (IR), visible and to some extent also ultra-violet (UV) radiation, is of importance to many current and future military applications. Propagation phenomena affect and often limit navigation, communications, surveillance, search, targe acquisition, fire control, autonomous weapons guidance, kill assessment, countermeasures and medium to high power laser applications. Recent advances in components and technology have prompted extensive studies and novel applications in the above wavelength region. Specifically, second generation infra-red detector technology, smart image processing, as well as active coherent detection systems, i.e. millimeter wave and laser radars, have required dedicated propagation studies, including much longer ranges over land and sea, multiple scattering effects and especially turbulence induced systems limitations. The following topics have been discussed: (1) Propagation measurements; (2) Propagation models; (3) Sensing of the propagation environment; (4) System aspects and performance modelling; and (5) Countermeasures. Keywords: Propagation models; Atmospheric absorption; Laser radar; Sensing; Performance modelling.
