Performance-driven resource management in layered sensing
Chun Yang, Ivan Kadar, Erik Blasch · 2009
Abstract- Layered sensing provides a hierarchical netcentric architecture for universal situational awareness with global coverage and persistent surveillance. Sensors in the layered hierarchy provide spatial, temporal, spectral, and polarization diversity with different scales and resolutions over different time horizons. Cooperative management of netted sensors is a successful strategy to achieve targeting performance and overall measures of merit (MOM) goals. After a brief introduction to issues in layered sensors, a resource management strategy based on geometry information is described so as to enhance performance in target detection (minimum detectable Doppler) and tracking accuracy (geometric dilution of precision). Preliminary simulation results are presented to illustrate this Geometric Approach to Layered Sensing (GALS) concept. the bottom layer, ground sensors can stay in the same area so long as the battery lasts but typically have limited spatial coverage.
