Research Topics


The Air-ASW Navy's current bistatic active processing system consists of the ADAR sonobuoy as a receiver for the IEER incoherent source. However, buoy to aircraft bandwidth limitations restrict the buoy's data band over which the aircraft processing can take place. In-Buoy Processing, however, eliminates that limitation, since it can access the data directly from the individual hydrophones, and thus have access to the full bandwidth of the individual sensors. This Phase I proposal provides an innovative approach to performance improvement by utilizing the extended data band to demonstrate gains in detection, bearing estimation, buoy and target location accuracy and classification performance.
