Project 6,3 - Effects of Atomic Explosion on the Ionosphere - M. A. Hawn
OBJECTIVE
The objective of Project 6.3 is to obtain dete on the effects of high
yield nuclear explosions on the Jonosphere.
Prinaipally, to investigete
the area of sbeorption, probebly due to the high altitude radicective
particles, and to study the effect of orientation relative to the earth's
magnetic field on F2 layer effects.
SESTRIRGETATICN
The_syatemcomrizes:
Two Ionosphere recorders, type C-2, operating on pulae transmission,
installed in 6 ton trailer vans, one located at Rongerik Atoll and one
located at Euseie in the Caroline Islands.
One Ionosphere recorder, type C-3, operating on pulse trananissico,
installed in a G97 plane based at Enivetok Island.
Description:
Ionosphere recorder site (Rongerik Atoll)
ite (Kusaie)
AH/CPQ-7, type C-2 Ionosphere recorder with a power output of
10 KW peak pulse alternately tranmitting ond receiving automstically over
the range of frequencies from ] to 25 megacycles,
This ecuippent measures
and records at vertical incidence the virtual height and critical
frequencies of fonised regions of the upper atmosphere.
