— In this paper we study the problem of dynamic optimization of ping schedule in an active sonar buoy network deployed to provide persistent surveillance of a littoral area through multistatic detection. The goal of ping scheduling is to dynamically determine when to ping and which ping source to engage in order to achieve the desirable detection(More)
A localization algorithm using radio interferometric measurements is presented. A probabilistic model is constructed that accounts for general noise models and lends itself to distributed computation. A message passing algorithm is derived that exploits the geometry of radio interferometric measurements and can support sparse network topologies and noisy(More)
The problem of optimized distributed detection in a system of networked sensors involves a number of design aspects, including balancing probabilities of missed detection and false alarm as well as managing the communication resources through proper in-network information fusion. Moreover, a number of tradeoffs must be exercised, such as the one between the(More)
miniaturized MALDI-TOF mass spectrometer has been in development at APL for the last several years. Besides meeting the mechanical design challenges in taking a bench-top–sized instrument and shrinking it down for easy and rapid deployment with autonomous operation, sample collection and preparation methods have been developed to analyze, detect, and(More)
