RF Unattended Ground Sensors (UGS) for Retargeting

A new family of munitions that can be retargeted in flight is being developed. In order to obtain timely and accurate target position and velocity information, new sensor arrays are needed. This proposal describes the use of a radar system to obtain the position and velocity information. Integrated with the radar system is a self-forming, networked radio system that performs the function of sensor node localization and transfer of information among nodes. Key design goals include small size, low cost, and the ability to operate from a battery for extended periods of time. Additionally, radar foliage penetration capability and use of a minimum number of GPS equipped nodes is important to the system design.
