Available in PDF, EPUB and Kindle. Book excerpt: Compact coherent CO2 laser radars have the potential for greatly improved angle, range, and velocity resolution relative to their microwave radar counterparts. This research program was aimed at obtaining quantitative understanding of target reflection and atmospheric propagation effects on such laser radars through a combination of theory and experiments. Toward those ends, improved statistical signal models were developed, and corroborated through measurements, for turbulence and speckle effects in 2-D pulsed imager operation. Speckle and clutter effects in 2-D Doppler imager operation were also studied through analysis and measurements. Possible bad-weather laser radar operation, using scattered light, was considered theoretically, but shown to require use of a different laser wavelength than the 10.6 micron CO2 laser wavelength. A theoretical study of the use of high time-bandwidth (TW) product signal waveforms in 3-D imaging radar was also performed. The experimental portions of the research were carried out under a collaboration arrangement with the Opto-Radar Systems Group at MIT Lincoln Laboratory. (Author).

Book Synopsis Atmospheric Propagation in the Middle-Infrared and at 8-14 Micrometers by : J. Stacey
Download or read book Atmospheric Propagation in the Middle-Infrared and at 8-14 Micrometers written by J. Stacey and published by . This book was released on 1973 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study considers the problems of propagation through the lower troposphere in the middle-infrared and in the 8 to 14 micrometer regions of the spectrum. The atmospheric constituents that scatter and absorb energy at these wavelengths are identified and the losses are calculated for several air-to-ground transmission paths. Examples of the atmospheric transmission losses are calculated for several passive sensor bandpasses and for a radar at 10.59 micrometers. In these examples, the atmospheric constituents that contribute to the total propagation loss over the sensor bandpass are individually identified and the accumulated losses are separately reported as a function of slant range. The performance for active and passive sensors is calculated and plotted for a host of weather conditions. Variations in rain rates, fog densities, and haze visibilities are introduced to demonstrate the relative degradation to the S/N for the sensor system. Aircraft measurements of atmospheric constituents are examined to determine if an empirical relationship exists between haze visibility and slant-path transmittance. Empirical expressions for haze attenuation are derived for selected wavelengths in the middle-infrared region and at 10.59 micrometers. Attenuation from common chemical smokes is estimated.

Download or read book 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 written by and published by . This book was released on 1990 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
