This test was designed to determine the suita bility of unmodified operational naval radar sets for Indirect Bomb Damage Assessment (IBDA) purposes and to provide fleet personnel with ex perience in the analysis of IBDA data. The Navy AJ-2 aircraft with a standard ASB-1 radar bomb ing system and an R4D-5Q aircraft equipped with an APS-31 radar set simulated attack aircraft during five shots. At the time of detonation, the aircraft were in a head-on flight about 7 miles from ground zero. The presentation of the nuclear detonations on the radar scope was photo graphed from approximately time zero to ten sec onds after detonation. Positive results were obtained from Shots 8 and 13. A detailed analy sis of the available data indicates that an in terim IBDA capability may exist with present equipment with minor modification, provided special attention is given to the features which produce good photographs for IBDA; that is, cor rect gain setting and sufficient identifying de tails to plot aircraft location.
