Project 6,4-+ Determination of Characteristics of Airborne Flush Mounted
Antennas and Phototube for Yield Determination at Extended
Ground to Air Ranges - A. J, Waters
1,
To determine the effectiveness of flush mounted airborne antennas
aad phototubes at various ground-to~-air ranges in detecting characteristic
low frequency electromagnetic raiiation and visible radiation, respectively.
2.
To determine the temporal and amplitude characteristics of the low
frequency electrosagnetic radiation at various ground-to-air ranges,
3.
To determine the temporal and intensity characteristics of visible
q
eijation at various ground-to-air ranges.
4.
To determine the effects of ambicnt coniitions upon the
;
satisfectory measurenent of the parameters specifiei in items 1 -nd 2

: POENTQUE
Signal is received by antenna fed through an amplifier and then to
he scope,
The signal is then photographed.
directly to the recorder,
Photc’ead cutput is led
The sequence camera photographs the blast
directly for use in correlation of previous data,
Distance was approx.
