Behavior of Four Sound Ranging Techniques in an Idealized Physical Environment.

摘要

Four contemporary sound ranging techniques are examined in an environment chosen to insure optimal performance characteristics for each. A data base is employed which is free of external contamination so that effects of truncation of arrival times and variations among algorithms are the sole contributors to observed differences in behavior. Noteworthy is the interplay which emerges between truncation effects and system response to meteorological errors. In addition, a direct comparison of techniques is given in context. (Author)
