Abstract:

Sandia National Laboratories has continued to evaluate the performance of infrasound sensors that are candidates for use by the International Monitoring System IMS for the Comprehensive Nuclear-Test-Ban Treaty Organization. The performance criteria against which these sensors are assessed are specified in Operational Manual for Infrasound Monitoring and the International Exchange of Infrasound Data. This presentation includes the results of efforts concerning two of these sensors 1Chaparral Physics Model 5 and 2CEA MB2000. Sandia is working with Chaparral Physics in order to improve the capability of the Model 5 a prototype sensor to be calibrated and evaluated. With the assistance of the Scripps Institution of Oceanography, Sandia is also conducting tests to evaluate the performance of the CEA MB2000. Sensor models based on theoretical transfer functions and manufacturer specifications for these two devices have been developed. This presentation will feature the results of coherence-based data analysis of signals from a huddle test, utilizing several sensors of both types, in order to verify the sensor performance.
