Abstract : A 100-megacycle, 1-megawatt, variable pulse width (1, 2.5 and 5 microseconds) radar, the AN/TPQ-20, was installed at the Stallion Site, White Sands, New Mexico, for the purpose of viewing and photographically recording A-scope displays of the Athena test vehicles. Vertically polarized signals were transmitted and two receivers used, one for vertically polarized and one for horizontally polarized signals. The vertical and horizontal signals were recorded photographically on a pulse to pulse basis, together with range time. Ancillary data was paper recorded on Brush recorders. The antenna consists of five yagis mounted on an azimuth elevation mount and pointed to the area of interest by slaving the entire mount to an FPS-16 or L/UHF precision radar. (Author)
