Description/Abstract:
THE PRIMARY OBJECTIVE OF THE PROJECT 6.13 DAMP SHIP ( USAS AMERICAN MA RINER ) PARTICIPATION IN THE FISH BOWL SERIES WAS TO MAKE RF MEASUREME NTS TO DETERMINE THE AMOUNT OF RADAR REFRACTIVE JITTER PRESENT IN A NU CLEAR BURST ENVIRONMENT. THE SECONDARY OBJECTIVES WERE: (1) MEASUREMEN T OF ELECTRON LINE DENSITY, (2) INVESTIGATION OF RADAR CLUTTER, (3) ME ASUREMENT OF RF NOISE PRODUCED AT ONE RADAR FREQUENCY, (4) MEASUREMENT OF ABSORPTION OVER A WIDE PORTION OF THE RF SPECTRUM, (5) STUDY OF TH E FIREBALL ON RADAR MEASUREMENT AT SEVERAL FREQUENCIES, (6) MEASUREMEN T OF FIREBALL REFLECTION AT EARLY TIMES ( BLUE GILL ), AND (7) MEASURE MENT OF DISSOCIATED REGION REFLECTIVITY ( STAR FISH PRIME ). OPTICAL M EASUREMENTS WERE MADE TO DETERMINE: (1) DAMAGE TO DIRECT OPTICAL VIEWI NG SYSTEMS, AND (2) SATURATION AND BLANKING OF INSTRUMENTATION VIEWING THE BURST REGION. ADDITIONAL MEASUREMENTS, IN SUPPORT OF OTHER PROJEC TS, WERE ACCOMPLISHED. A SUMMARY OF THE DATA ON THE FIVE EVENTS PROVES CONCLUSIVELY THAT THE EFFECTS OBSERVED WERE BOTH SERIOUS AND OF LONGE R DURATION THAN PREVIOUSLY SUSPECTED, BUT VARIED CONSIDERABLY WITH YIE LE AND ALTITUDE. IT WAS DEMONSTRATED DURING THE BLUE GILL TRIPLE PRIME EVENT THAT LOSS OF PRECISION TRACKING DATA MAY BE INCURRED UP TO FIVE AND A HALF MINUTES AFTER BURST, DUE TO FLUCTUATIONS IN THE APPARENT A NGLE OF ARRIVAL OF THE TARGET SIGNALS IN THE NUCLEAR ENVIRONMENT ( ANG ULAR JITTER ). ALTHOUGH, FOR ALMOST EVERY TEST, INSTANTANEOUS SINGLE-P ULSE EFFECTS AT H-0 WERE OVERWHELMING, THE LONGER LASTIN 20 - TO 30 - DECIBEL ATTENUATIONS OBSERVED THROUGH DEBRIS REGIONS SEVERAL MINUTES A FTER BURST WERE VERY SIGNIFICANT. THESE MEASUREMENTS ARE FAR MORE SIGN IFICANT IN APPLICATION TO A PASSIVE RADAR SYSTEM WHEN IT IS CONSIDERED THAT THEY REPRESENT THE ONE-WAY PROPAGATION EFFECTS OF A TRACKED BEAC ON TARGET RATHER THAN PASSIVE SKIN TRACK. OF EVEN MORE IMPORTANCE IN I TS APPLICATION TO THE FIELD OF TARGET DISCRIMINATION IS THE APPEARANCE OF TENS OF DECIBELS OF NOISELIKE SIGNAL FLUCTUATION OCCURRING FOR PER IODS LONGER THAN 10 SECONDS AFTER BURST. THIS REPORT CONSISTS OF SEVEN VOLUMES, THIS VOLUME, PLUS ONE VOLUME FOR EACH OF THE FIVE FISH BOWL EVENTS AND A VOLUME COVERING OTHER SELECTED DATA (SEE PREFACE).
