Algorithm to Emulate RF Signal of Multiple Targets for Countermeasures Technique Assessment

Long-range semi-active Surface to Air Missiles (SAM), Air-to-Air Missiles (AAM), and Air-to-Air Anti-Radiation Missiles (AA-ARM) represent a threat to US aircraft. These missile guidance systems employ monopulse antennas and receivers which are less vulnerable to conventional Electronic Attack (EA) techniques. Conventional EA techniques coupled with sophisticated angle countermeasures can increase the success of U.S. Forces counter air operations (offensive and defensive), theater missile defense, and suppression of enemy air defenses. The development and testing of EA countermeasures is very expensive. Man/hardware-in-the-loop laboratory simulation is the most cost-effective methodology for evolving/maturing advanced EA countermeasure technologies because the battlefield can be brought to the laboratory through multi-spectral synthetic battlespace simulation. Current laboratory RF threat environment simulators do not provide the required fidelity to accurately simulate the parameters needed to develop these advanced EA countermeasure techniques. DRA proposes to solve this challenging technology limitation by developing an innovative solution to control (steer) the RF signals within the Triad antenna array network (AAN) to support the advanced countermeasure development. During Phase I, DRA will develop a top level design and conduct a proof of concept demonstration of key technology element. During Phase II, DRA will develop a prototype capability and demonstrate key performance characteristics.
