Abstract : To fill the Air Force's need for a low-cost-per-channel instrumentation system to accurately measure the propagation of soil stress waves, an experimental 6-channel Time-of-Arrival system was developed. Upon delivery of this prototype system to the Air Force Weapons Laboratory, an evaluation program was initiated to determine its feasibility. Because of the success of the prototype system a 100-channel system was constructed by the AFWL. This upgraded system was used successfully in a simulated nuclear test experiment at Kirtland AFB, New Mexico on 15 December 1964. (Author)
