Abstract : The report describes a study conducted to determine the motion of the structure and foundation during antenna operation for the: (a) TAA-2A radar tower, Vero Beach, Florida, and (b) TAA-3 antenna, Merritt Island, Florida. Specifically, these tests determined the magnitude and direction of displacement, natural frequencies, phase of movement, and attenuation characteristics of the structure and foundation. These tests were performed using maximum programmed antenna accelerations, velocities, and decelerations, which were recorded for correlations. Motion in three planes--vertical, radial, and tangential--was monitored at different transducer locations by means of velocity-type pickups. Theoretical procedures described in EM 1110-345-310 were used to predict the frequencies and displacements that would occur. (Author)
