N2  - Much work has gone into characterizing the blast wave, and ultimate acoustic pulse, produced by an explosion in flat, open land. Recently, an experiment was performed to study signals produced by explosions in more complex environments, both above and below ground and in the vicinity of mountainous terrain. Explosive charges, ranging in weight from 200 to 2000 lbs, were detonated in a variety of configurations in and around tubes and culverts as well as buried in alluvium and limestone. A large number of acoustic sensors were deployed to capture the directivity of the signals in the near-field and to characterize the propagation of the signal to the far field. Significant directivity was observed in the near field signals from many of the shots. The influences of both meteorology and topography were evident.<p />  <p>Language: en</p>
