1. Broad Technical Challenge
Flat sensor response in intermediate spectral range
(at least Hz, up to Hz)
Ease of emplacement and ability to function in variety of difficult geologic and environmental conditions
Flexibility in application
Small size of total instrument package (with sensor support)
Low sensor self-noise (below USGS New Low Noise Model)
Stable instrument response with calibration
Dynamic Range > 120dB
Linear Response > 60dB
Power Consumption < 100 mW
Ideally Three Orthogonal Components
Current standard solutions:
- Geophone (small, easy, flexible)
- Classical Seismometer (flat response, low self noise, stable)
