Modern passive acoustic-seismic monitoring system – The 5DQM-concept

Januar 2020 | E. D. Rode, S. Marinello

Passive monitoring technologies are those that detect and compile “background noise” emissions across a wide span of wavelengths and do not generate a signal themselves. They depend on the cognitive interpretation of all background noise and are, therefore, broadband communication/detection systems. They require very highly sensitive sensory perception capability and very advanced signal processing, analysis and interpretation. They are used to detect and monitor, which means they provide information about the localization and the nature of target and its contemporary and predictive behavior across time.
