<span>The pulse ultra-wide band (UWB) radar consists of switching energy very short duration in an ultra-broadband emission chain, and the UWB signal emitted is ultrashort pulse, order nanoseconds, without a carrier. These systems can indicate presence distances distant object, call target, determine its size, shape, speed, trajectory. In this paper, we present system allowing detection t...

Localization capabilities are necessary for autonomous robots that need to keep track of their positionwith respect to a surrounding environment. A pursuit robot is an autonomous robot that tracks and pursues a moving target, requiring accurate localization relative to the target’s position and obstacles in the local environment. Small unmanned ground vehicles (SUGVs) equipped with a monocular ...

We are developing an acoustic habitat-monitoring sensor network that recognizes and locates specific animal calls in real time. In this paper, we investigate the system requirements of such a real-time acoustic monitoring network. We propose a system architecture and a set of lightweight collaborative signal processing algorithms that achieve real-time behavior while minimizing inter-node commu...

Fault-tolerant target detection and localization is a challenging task in collaborative sensor networks. This paper introduces our exploratory work toward identifying the targets in sensor networks with faulty sensors. We explore both spatial and temporal dimensions for data aggregation to decrease the false alarm rate and improve the target position accuracy. To filter out extreme measurements...

This paper presents an approach to near-optimal target localization for small and micro uninhabited aerial vehicles using a family of pre-computed parameterized trajectories. These trajectories are pre-computed for a set of nominal target locations uniformly distributed over the sensor field of view and stored off-line. Upon target detection the vehicle chooses the trajectory corresponding to t...
