Lewis CPeTeT Ive To utilize the electromagnetic signal originating from nuclear weapon detcnations to determine ground ecro cf detonation. Ne we we a am? Secondarily vc obtain the yicld data thet fe available in the bomb pulse, tion of ercund zero is made by use of an inverse Leran principle. The exact time the bomb pulse is received at various stetions is recorded. The exact time difference in receirt of the electromagnetic pulse betwerp ine a hyporteclic curve which runs) 4 two stations will be used to dete through ground zere. - The point of intersoeticn of two or more curves cLermines ground zero, RLoTTrTe with the execption of Griffies AFP all stations in both the long nd short hase line successfully received and recorded the wave form of pulse emanating from the bomb detonation. ‘Sg the electrcomagnetic Line of position and fix errors will be reported later.
