Project 6.4 + Determination of Characteristics of Airborne Flush Mounted
Antennas and Photo Tubes for Yield Determination at
Extended Ground-to-Air Ranges - A, J. Waters
OBITSTIVES
To determine the effectiveness of flush mounted airborne antennas
and phototubes at various ground-to-air ranges in detecting character~
istic low frequency electromapnetic radiation and visible radtation,
respectively,
To determine the temporal and amplitude characteristics of the low
frequency electromagnetic radiation 2t various ground-to-air ranges.
To jietermine the temporal and intensity characteristics of visible”
radiation at various grcound-to-2ir ranges.
To determine the effects cf ambient conditions upon the satisfactory
measurement of the paramcters specified in items ] and 2 above.
INSTRUMENTATION
2 fiducial antennas
1 scope camera
1 synchronizer
1 DuMont Seope (dual bean)
TUAMNIQUe
Signal is received by antenna fed through an amplifier and then to
the scope,
The signal is then photographed.
dircetly to the recorder.
Photohead output is let
The sequence camera phctoprephs the blast
directly for use in correlation of previous data.
Distance was approx-
imately 10 miles,
RESULTS
Equipment was removed from plane and set up at Parry Island on
