Abstract : In 1985, Cooley Electronic Laboratory (CEL) in conjunction with the Scripps Institution of Oceanography (SIO) and Woods Hole Oceanographic Institution (WHOI) measured the pulse responses of three acoustic sources used, or to be used, in making ocean acoustic propagation measurements. The three sources were the Hydroacoustics HLF-5 250 Hz (DW-224) source. THe basic goal of these measurements was to observe the source outputs at close range in a relatively controlled situation. Of particular interest were: 1) the source pulse response, 2) the time delay through the source 3) the presence or absence of spurious pulses (artifacts).
