The detection of known signals in colored Gaussian noise typically involves applying a matched filter to prewhitened data samples in the discrete-time domain. This is achieved by sampling the continuous-time data and applying a prewhitener before app

A new method is derived for finding the best positions in which to locate the sensors in a distributed sensor network in order to achieve a desired variation, or pattern, in spatial coverage over a specified domain. Such patterning is important in si

We develop an optimization approach for the planning problem of configuring the positions of sensors within a sensor network for minimization of the travel length required to service the sensor locations. This is in contrast to existing approaches wh

The use of a spatially distributed set of sensors has become a cost-effective approach to achieve surveillance coverage against moving targets. As more sensors are utilized in a collaborative manner, the optimal placement of sensors becomes critical

The focus of this article is to study methods for information-based planning of sensor configurations for use in source localization. Given a bounded region of interest, for each individual (plausible) source location, we define a performance measure

We consider the optimal deployment of a sparse network of sensors against moving targets, under multiple conflicting objectives of search. The sensor networks of interest consist of sensors which perform independent binary detection on a target, and

Particle filters represent the current state of the art in nonlinear, non-Gaussian filtering. They are easy to implement and have been applied in numerous domains. That being said, particle filters can be impractical for problems with state dimension

When unmanned distributed sensor fields are developed for rapid deployment in hostile areas, the deployment may consist of multiple sensor types. This occurs because of the variations in expected threats and uncertainties about the details of the loc
