Radiation surveillance using an unmanned aerial vehicle.

Unmanned aerial vehicle field sampling and antenna pattern reconstruction using Bayesian compressed sensing

Antenna 3D pattern measurement can be a tedious and time consuming task even for antennas with manageable sizes inside anechoic chambers. Performing onsite measurements by scanning the whole 4π [sr] solid angle around the antenna under test (AUT) is more complicated. In this paper, with the aim of minimum duration of flight, a test scenario using unmanned aerial vehicles (UAV) is proposed. A pr...

Reconnaissance and Surveillance in Urban Terrain with Unmanned Aerial Vehicles

Unmanned vehicles endowed with attributes of intelligence are finding applications in reconnaissance, surveillance, and rescue operations in both military and civilian domains. We are introducing a methodology to locate a number of such Unmanned Aerial Vehicles (UAVs) optimally over an urban environment and identify and track potential ground targets using a particle filtering framework. The pa...

Cooperative Surveillance and Pursuit Using Unmanned Aerial Vehicles and Unattended Ground Sensors

This paper considers the problem of path planning for a team of unmanned aerial vehicles performing surveillance near a friendly base. The unmanned aerial vehicles do not possess sensors with automated target recognition capability and, thus, rely on communicating with unattended ground sensors placed on roads to detect and image potential intruders. The problem is motivated by persistent intel...

Mission Health Management for 24/7 Persistent Surveillance Operations

This paper presents the development and implementation of techniques used to manage autonomous unmanned aerial vehicles (UAVs) performing 24/7 persistent surveillance operations. Using an indoor flight testbed, flight test results are provided to demonstrate the complex issues encountered by operators and mission managers when executing an extended persistent surveillance operation in realtime....

TELEOPERATED VISUAL INSPECTION AND SURVEILLANCE WITH UNMANNED GROUND AND AERIAL VEHICLES Teleoperated Visual Inspection and Surveillance with Unmanned Ground and Aerial Vehicles

This paper introduces our robotic system named UGAV (Unmanned Ground-Air Vehicle) consisting of two semi-autonomous robot platforms, an Unmanned Ground Vehicle (UGV) and an Unmanned Aerial Vehicles (UAV). The paper focuses on three topics of the inspection with the combined UGV and UAV: (A) teleoperated control by means of cell or smart phones with a new concept of automatic configuration of th...
