A common theme underlying the research these groups conduct is the use of propagating waves to detect, locate, image or otherwise identify features of the environment significant to their applications. The applications considered in this symposium are verification of nuclear test ban treaties, non-destructive evaluation (NDE) of manufactured components, and sonar and electromagnetic target acquisition and tracking. These proceedings cover just the first two topics. In these applications, arrays of sensors are used to detect propagating waves and to measure the characteristics that permit interpretation. The reason for using sensors arrays, which are inherently more expensive than single sensor systems, is twofold. By combining the signals from multiple sensors, it is usually possible to suppress unwanted noise, which permtis detection and analysis of waker signals. Secondly, in complicated situations in which many waves are present, arrays make it possible to separate the waves and to measure their individual characteristics (direction, velocity, etc.). Other systems (such as three-component sensors in the seismic application) can perform these functions to some extent, but none are so effective and versatile as arrays. The objectives of test ban treaty verification are to detect, locate and identify underground nuclear explosions, and to discriminate them from earthquakes and conventional chemical explosions. Two physical modes of treaty verification are considered: monitoring with arrays of seismic stations (solid earth propagation), and monitoring with arrays of acoustic (infrasound) stations (atmospheric propagation). The majority of the presentations represented in these proceeding address various aspects of the seismic verification problem.
