GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: The purpose of this investigation was to determine the adequacy of the irradiation area, time variation of irradiance, and spectrum of the laboratory sources employed in evaluating the protection afforded to personnel by military clothing. The primary objective of measuring the radiant exposure and irradiance histories at the earth’s surface was attained, except for the resolution of the irradiance histories in the early phase of the pulse and the precise determination of the radiant-exposure values for the obscured station for Shot Teak and the airborne station for Shot Orange. For general studies of effects of thermal radiation from high-altitude nuclear bursts, the documentation of the stimulus in future field tests should include better time resolution in total-irradiance measurements and some spectral breakdown of the irradiance history.

X-band radar determination of nuclear-cloud parameters Corporate Source: Army Signal Research and Development Lab., Fort Monmouth, NJ Publication Date: Report Number(s): Document Type: (USA) 1 Sep 1985 p 36 AD-A-995388/6/XAB Report Language: English Journal Announcement: EDB8611 Availability: NTIS, PC A03/MF AOl. Subfile: ERA (Energy Research Abstracts). GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: The general objectives of this project were to make observations with weather Radar Set AN/CPS-9 in order to determine what characteristics and parameters of a nuclear detonation could be detected with X-band radar. The specific objectives were to obtain data that would lead to the determination of the following information . relative to the nuclear cloud; rate of rise, rate of horizontal ‘growth, maximum height, maximum diameter, stabilized height, fallout pattern due to the initial cloud formation, and range and azimuth versus time. AS a result of this project, it was determined that the AN/CPS-9 radar is well suited for observations of surface or near-surface bursts, as would be expected from a comparison of its performance characteristics _ with those'of other available radar sets.
