Method for Real-Time Signal Selection for Passive Coherent Location Systems [PDF]

open access: yes, 2017
Passive coherent location (PCL) systems use signals of opportunity to perform traditional radar detection, targeting, and tracking functions. Traditionally these signals include FM radio, digital TV, GSM, and GPS because of their availability in most ...

The Analysis of Sophisticated Direction of Arrival Estimation Methods in Passive Coherent Locators [PDF]

open access: yes, 2002
In passive coherent locators (PCL) systems, noise and the precision of direction of arrival (DOA) estimation are key issues. This thesis addresses the implementation of sophisticated DOA estimation methods, in particular the multiple signal ...

Actor-network procedures: Modeling multi-factor authentication, device pairing, social interactions

open access: yes, 2011
As computation spreads from computers to networks of computers, and migrates into cyberspace, it ceases to be globally programmable, but it remains programmable indirectly: network computations cannot be controlled, but they can be steered by local ...
