Project 6.4 - Determination of Characteristics of Airborne Flush Mounted
Antennas and Phototubes for Yield Determination at Extend-
ed Ground-to-Air Ranges - Allan J, Waters
Objectives
To determine the effectiveness of flush mounted airborne antennas
and phototubes at various ground~to-air ranges in detecting characteristic low frequency electromagnetic radiation and yisible
radiation,
respectively.
To determine the temporal and amplitude characteristics of the low
frequency electromagnetic radiation at various ground-to-air ranges.
To determine the temporal and intensity characteristics of visible
radiation at various ground-to-air ranges,
To determine the effects of ambient conditions upon the satisfactory
measurement of the parameters specified in 1 and 2 above,
Instrumentation
2 fiducial antennas
1 sychronizer
1 scope camera
1 DuMont scope
Technique
Signal is received by antenna fed through an amplifier and then to
the scope.
The signal is then photographed.
