Abstract
Radar echoes have been observed during previous atomic detonations but with little additional data. Measurements on echo intensity and characteristics were obtained and recorded by use of an X-band radar system. To accomplish the desired results, the video signals from the AN/APQ-24 radar receivers, one located in each of two B-50D aircraft, were displayed on a calibrated oscillograph and photographed with a low-speed conventional 35-mm movie camera at 32 frames/sec and a modified General Radio 651 AE oscillograph camera operating at 27 ft/sec. The radar signals were displayed on a DuMont 294-A oscillograph with a 5xP11 cathode-ray tube operating at a 12-kv acceleration voltage to obtain sufficient light intensity for recording. The photographic recordings thus obtained were used for further analysis to determine the value of the data. (MM)
