Project 6.4 = Determination of Characteristics of Airborne Plush
Mounted Antennas and Photo Tubes for Yield Deterwinstior
at Extended Ground-to-Air Ranges - A, J, Waters
OBJECTIVES
To determine the effectiveness of flush mounted airborne antennas
and phototubes et various ground-to-air ranges in detecting characteristic
low frequency electromagnetic rafiation an! visible radiation, respectively.
To determine the temporal end amplitude characteristics of the low
:
frequency electromagnetic radiation at various groumi-te-eir ranges.
To determine the temporal and intensity characteristics of visible
radiation at various ground-to-air ranges.
To determine the effecta of ambient comiitions upon the satisfactory
measurement of the paremeters specifie! in the ‘irat two items.

DuMont Scopes (1 a 4ual beam,
2 scope cameras
1 sequence camera
1 recorder
1 a single bean)
TEGHPIQUE
Signal ie received by antenna fed through an emplifier ar then to
the scope.
The signal ie then photographed,
t the recorder,
Photohead output is led directly
The sequence cemers photographs the blast ‘tirectly for use
in correlation of previous data,
Distance was approximately (2 miles.
RESULTS
The signal ves received ant recorie’ by one fiducial antenna apd one
woe.
BEST AVAILABLE COPY
Ne photohead date was obtained beceuse of a bulb failure in the recorder.
