AESA-based RADAR Performance in Complex Sensor Environments Navy SBIR FY2006.2 Sol No.: Navy SBIR FY2006.2 Topic No.: N06-123 Topic Title: AESA-based RADAR Performance in Complex Sensor Environments Proposal No.: N062-123-0598 Firm: Toyon Research Corp. 6800 Cortona Drive Goleta, California 93117-3021 Contact: Kevin Sullivan Phone: (805) 968-6787 Web Site: www.toyon.com Abstract: Toyon proposes to develop a dynamic sensor tasking module (DSTM) for AESA radars that explicitly considers mission objectives when selecting sensor tasks. We will employ a finite-horizon feedback approach where we plan tasks for a specified time interval and then replan once that interval has expired, using new information that we have collected about the battlespace. Our approach will take into consideration ownship survivability, the engagement of targets, the search for undiscovered targets, and the prevention of fratricide. We have developed a dynamic sensor tasking module in support of the Joint Strike Fighter program that we plan to leverage for this effort. The key new work that will be done in Phase I of this effort will involve the formulation, integration, and evaluation of a new objective function. We will use a Toyon-developed simulation called TADSim to evaluate the performance of the new objective function. We will analyze the performance of the DSTM with the new objective function using scenarios that we are currently using to support JSF, or, we will use scenarios supplied by the Navy. To model the radar, we will use our current JSF radar model, or, we will use a model specified or provided by the Navy. Benefits: The successful completion of this research will result in a sensor manager that is able to control an AESA radar so that its capabilities can be fully utilized. This will result in greater numbers of targets that can be engaged, greater ownship survivability, and reduced chances of fratricide. These algorithms also have potential non-military applications in the commercial domain involving resource management for communication systems. Return
