Project (.4 - Determinetion of Characteristics of Airborne Flush Mounted
Antennas end Photo Tubes “or Yield Determination at Extended
Ground-toeAir Ranges - A. J. Waters
OBJECTIVES
To determine the effectiveness of flush mounted airborne antennas and
phot otubes at various ground-to-air ranges in detecting characteristic low
frequency electromagnetic radiation and visible radiation, respectively.
To determine the tempora] and arplitude characteristics of the low
frecuency electromagnetic rediation at warious ground-to-sir ranres.
To determine the temporal sod intensity characteristics of visible
radiation at warious cround-to-eir ranges.
To determine the effects of ambient conditions upon the satisfactory
measurement of the perancters specifiod 1: the first two items,
