Abstract:

A prime objective of the experiment was the quantitative measurement of the attenuation suffered by radar beams passing near or through the fireball of a nuclear detonation. During the test series, measurements were also made of effects produced in regions not directly associated with the fireball proper. A second prime objective of the experiment was to investigate possible phase differences which were expected to develop in nearly parallel radar rays passing through ionized regions. Ballistic rockets were used to place CW beacons, radiating at 1-, 5-, and 10-kMc frequencies. Five receiving stations, four on ships and one on Johnston Island, made signal strength measurements. An interferometer on the island made phase-front measurements at 1- and 5-kMc.
