OPTIMIZATION OF AN EFFICACIOUS TUMOR VASCULAR THROMBOGEN

Not Available The U.S. Navy dependence on GPS continues to increase, making it imperative to protect the GPS signals from radio frequency interference (RFI). Spatial nulling by CRPA systems is very effective at countering these RFIs, however, current CRPA systems are large and expensive, therefore unsuitable for current and future airborne platforms. The present SBIR Phase I proposal addresses this Navy requirement and proposes a Small Tactical L1/L2 CRPA (equivalent to 5 diameter circular array) Antenna Array and Electronic Control (STAEC) employing spatial-temporal processing architecture that provides cost-effective anti-jam capabilities. The small antenna array and digital antenna electronics design derives its legacy from a proven Mayflower GPS adaptive antenna solution. The proposed STAEC solution employs a novel signal processing approach that is effective against wideband jammers and aircraft multipath. The Phase I research will include modeling and simulation of the antenna array, as well as prototype antenna array measurements in anechoic chambers to demonstrate the performance of the small array by generating measured data of key system elements. The Phase II program will design, fabricate and demonstrate a prototype STAEC unit consisting of the small array and the digital beamforming/nulling electronics. The cost goals for the STAEC unit will be validated in Phase II.
