Wave Scattering and Sensing Strategies in Intermittent Terrestrial Environments

Abstract

This research has two main components: (1) a new, wavelet-based cascade model for intermittent (uneven) distributions of objects in terrestrial environments and (2) a complementary analysis of intermittent wave scattering. Taken together, these developments facilitate realistic statistical descriptions of the performance range (uncertainty) associated with sensing and communication systems. The wavelet cascade model uses a simple set of decay processes to generate complex random media with realistic organization of objects in space and time. It is used to recreate the complex geology of the lava flow field around the Amboy Crater, CA, and incorporated into simulations of seismic wave propagation for this site. The simulations reproduce well the signal travel time distributions recorded along a sampling of 864 separate propagation paths.
