Project 6.1 - Accurate Location of an Electromagnetic Pulse Source E. A. Lewis
Ob jective
To utilize the electromagnetic signal originating from nuclear weapon
detonations to determine ground zero of detonation.
Secondarily to obtain
the yield data that is available in the bomb pulse,
Procedure
Location of Ground Zero is made by use of an inverse Loran principle.
The exact time the bomb pulse is received at various stations is recorded,
The exact time difference in receipt of the electromagnetic pulse between
two stations will be used to determine a hyperbolic curve which runs
through ground zero,
The point of intersection of two or more curves det-
ermines ground zero.
There are two systems,
One of the systems is know as the long base
line system and the other, the short base line system,
two sets of stations.
Each system has
The long base line has one set of stations located
in the Hawaiian Islands (Midway, Palmyra and Maui) with synchronizing
anterna station at Haiku, Maui, and the other set of stations in the States
(Harlingen,Texas; Blytheville, Arkansas; Kinross,Michigan and Rome, New York)
with synchronizing antenna station at Cape Fear, North Carolina,
The short
bése lines have one set of stations located in the Hawaiian area (Kona, Hawaii;
Papa, Hawaii; and Red Hill, Maui) the other set in California (Pittsburgh,
Woodland, and Maryville).
