Results of Explosive Array Measurements, September 1978

Abstract

As part of a larger active detection exercise a series of measurements was undertaken to ascertain the performance of explosive array sources. The explosive arrays consisted of four types, each having ten charges separated by lengths of fuse. Each array was 100 feet long and detonated by the pressure switch from a SUS charge. Two types of arrays were used predominantly; ten, four-pound charges detonated at a depth of 2500 feet with a primacord fuse (type P), and the same as above but with a mild detonating fuse and boosters (type M). To measure the performance of these arrays, specially modified sonobuoys were placed on the main beam of each array. This technique provided a useful solution to a normally difficult measurement problem. In addition, a hydrophone located near the sea surface directly over the array was monitored. In all tests the geometry, detonation timing, number of detonations per array, pressure levels, energy source levels (ESL) and beamforming performance were measured.
