OBJECTIVE
To utilize the electromagnetic signal originating from nuclear
weapon detonations to determine gound 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 inter-
section of two or more curves determines ground zero.
There are two systems,
One of the systems is known as the long
base line system and the other, the short base line system.
system has two sets of stations,
Fach
The long base line has one set of
stations located in the Hawaiian Islands (Midway, Palmyra and Maui)
with synchronizing antenna 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 base lines have one set of stations
located in the Hawaiian area (Kona, Hawaii; Papa, Hawaii; and Red Hill,
Maui) the other set in California (Pittsburg, Woodland, and Maryville).
RESULTS
Short base line.
