Project €.4 ~ Determination of Characteristics of Airborne Plush Mounted
Antennas and Photo Tubes for Yield Determination at Extended
Ground-to-Air Ranges - 4. J. Waters
OBJECTIVES
To determine the effectiveness of flush mounted airberne antennas
end photetubes at various ground-to-elir ranges in detecting characteristic
low frequency electromagnetic radiation and visible radiation, respectively.
To determine the temporal and amplitude characteristics of the low
frequency electromagnetic radiation at various ground-to-air renges.
To determine the tempera) and intensity characieristios of visible
rediation at warious ground-to-alr ranges.
To determine the effects of ambient oorditions upon the satisfactory
measuremert of the parameters specified in the first tvo items,
TESTROMENT
2 fiducial antennas
