Abstract
NETROLOGIC WILL USE THE CONTINUOUS WAVELET TRANSFORM TO OPERATE ON SEISMIC SIGNALS IN PHASE I. WE WILL USE THE CWT TO PRODUCE A SYTHESIZED SIGNAL WHICH IS REPRESENTED WITH ELEMENTS OF BOTH TIME AND FREQUENCY DOMAIN. THIS REPRESENTATION WILL BE FED TO A CASCADE CORRELATION NETWORK WHICH WILL BE TRAINED TO DETECT THE WAVEFORM WHICH IS INDICATIVE ON ONSET OF A REGIONAL EVENT. THIS TECHNIQUE WILL BE INTERFACED WITH THE IMS SYSTEM TO ALLOW IT TO AUTOMATICALLY MONITOR MANMADE SEISMIC EVENTS. IN PHASE II WE WILL DEVELOP SOFTWARE TO TEST NEW CONCEPTS USING THE IMS AND CONDUCT TESTS IN CONJUNCTION WITH THE STAFF AT THE DARPA CENTER FOR SEISMIC STUDIES. ANTICIPATED BENEFITS/POTENTIAL APPLICATIONS - IN OPERATION THIS SYSTEM WILL BE CAPABLE OF REAL TIM MONITORING AND ALARM WHEN SEISMIC EVENTS INDICATIVE OF NUCLEAR EVENTS ARE DETECTED. IT WILL BE A PERMANENT AND VALUABLE ADDITION TO THE IMS TOOL BOX.
