Abstract:

"Under Phase I array-processing techniques were developed andanalyzed which provided an effective interference rejectioncapability for acoustic intercept systems. This was demonstratedvia computer analysis and simulation of these techniques asapplied to a volumetric acoustic intercept sensor. It was shownthat, using such an array, an adaptive spatial normalizationtechnique could be used to suppress steady state and high dutycycle interference sources. Interference from such sources is amajor problem affecting existing systems. Under Phase II adeployable acoustic intercept alertment prototype processor willbe fabricated and tested which employs automated interferencerejection. The spatial cancellation techniques developed forPhase I will be integrated with processing for post detection,localization and classification of interfering sources. Thismulti dimensional spatial, temporal, and spectral interferencerejection approach will be designed to operate against a fullcomplement of interference source types. This integrated conceptwill be tested against available wide band sensor data, includingdata from the AN/WLR-9 and AN/SQQ-89 (V)15 MFTA ACI sensors, andalimited demonstration array for tank testing.BENEFITS: The technology demonstrated under this project will allow an acoustic intercept system to provide detection, classification and localization capability throughout a weapon engagement scenario. Thiswill allow the development
