The goal of the Demo III Program for Experimental Unmanned Vehicles (XUVs) is to develop and integrate technologies to provide a vehicle platform with autonomous capabilities. The platform will allow for the integration of modular mission packages to allow it to serve multiple needs across the battlefield. For demonstration purposes, the primary mission package will perform the functions of Reconnaissance, Surveillance, and Target Acquisition (RSTA). The RSTA mission package will provide the capability to conduct RSTA functions while both stationary and on the move. It will include a variety of sensor technologies along with signal and image processing capabilities to perform the RSTA mission. The paper will describe goals for the Demo III RSTA mission package, discuss the types of sensors being considered for platform integration, and summarize the RSTA related aspects of the recently awarded integration contract. Processing and algorithm capabilities required for the XUV to perform RSTA in an autonomous fashion, such as aided target recognition, motion detection, motion detection on the move, etc. will also be discussed.
