nen vou Sitios Project 6,4 - Determination of Characteristics of Airborne Plush Mounted Antennas and Photo Tubes for Yiald Determination at Extended Ground-to-Air Ranges - A.J. Waters QRIECTIVES To deteruine the effectiveness of flush mounted airborne antennas and phototubes at warious ground-to-elr ranges in detecting characteristic low frequency electromagnetic radiation and visible radiatice, respectively. To determine the temporal end amplitude characteristics of the low frequency electromagnetic rediation at various ground-to-air ranges. To determine the tesporal and intensity ebaracteristics of visible rediation at verious ground-to-air ranges. To determine the effects of amtiest eonditions upon the satisfactory measurement of the parameters specified in the first two items. TESTRREAT 2 fidueial antennas 2 scope cameras 1 eynebroniser 1 sequence camera 2 photobeeds 1 recorder 2 DuMont Scopes (1 a dual beam, 1 @ single been) TG Signal is received by antenna fed through an emplifier and then to the seope. The signa] is then photographed. direetly to the recorder, Photohead output is led The sequence scanmera photographs the blaat directly for use in correlation of previous data, Distance ves approximately 62 miles. BESULIS Signals vere received on both antennas. However, because of improper scope settings, excessive hash was photographed along with eignal on ope P o C E L S S A L I A V A T BES . otott ~ 53 = wae, 53 6
