RV4 Moving Target Identification Published May 10, 2010 By Mike McConkey Sensors WRIGHT-PATTERSON AIR FORCE BASE, Ohio -- Air Force Research Laboratory conducted a successful flight demonstration of Radar Vision 4, an important new capability for automated cueing and recognition of combat moving targets. Developed under the Air-to-Ground Radar Imaging Advanced Technology Demonstration, RV4 employs radar-based high-range resolution technology to identify moving targets. Working with 13 different vehicle types in various convoy arrangements, researchers demonstrated real-time execution of RV4 using the Raytheon Multiprogram Testbed, which is actually a modified Boeing 727 aircraft. The chief purpose of this demonstration effort was to exercise the RV4 capability in real time, as well as to verify earlier test results from the AGRI ATD (completed in October 2008). Accordingly, the researchers collected and recorded all radar, HRR, and algorithm data in order to facilitate precise playback and analysis of each RMT pass in the laboratory. Postprocessing of this assimilated data will play an essential role in verifying key performance parameters for the newly demonstrated capability. In addition to fulfilling the primary goal of verifying real-time performance and previously acquired test data, this RV4 technology demonstration also generated promising results with respect to the use of surrogate radar data for algorithm training, an application that could potentially reduce associated database costs.
