CHAPTLR 6 PROGRAM 7_-— LONG RANGE DETECTION 6.1 Project “umber: 7.1 Title: Electromagnetic Radiation Nae Sponsor: USAF ; oject Officer: 6.1.1 Calibration Nr.-J. A, Crocker Gbijective To determine the charagténistics of the electromignetic pulses from nuclear detonations as aifuiction of distance from the source. 6.1.2 Procedure Equipment will be trailer moet ed and located in an area of low background noise; at the present, Yoedtion is planned on Elmer. Fast sweep oscilloscopes with still and stripfilm data. recording will cover the range of frequencies emitted. Additipnal stations outside the Task Force area will be established along northerly and easterly azimuths to obtain supplemental data relating to attenuation. 6.1.3 Remarks hd Cne trailer will be located on =lmer and wild; require positioning and utilities. In addition, a tent or other suitabjle office facility has been requested. ‘tudio time notifications planned for =lmer will be utilized. Telegraphic advices of changes in schedulle andnotification thet the detonations have occurred are required to specified addressees. After-the-fact knowledge of world time of detonation, accurate to the nearest millisecond, will be required. World time is defined herein as receipt of radio signals from ‘"/VH, 41
