Project 6.1 - Accurate Location of an Flectromarnetic Pulse Source - E.A. Lewis
QRIECTIVE
To utilise the electromagnetic signal originatinre from nuclear weapon
detonations to determine ground sero of detonation,
Secondarily to obtein
the yield dete thet is available in the bord pulec.
PROCEDURE
Location of ground zero is made by wee of an inverse Loran principle.
The exact time the bomb pulse is received et 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 cro.
The point of intersection of tvo or more curves determines
ground serc.
There are two systems.
One of the systems is known as the long base
line system and the other the short base line system.
