Coherent array processing of gps sonobuoys

Underwater target tracking in ocean environment has attracted considerable interest in both military and civilian applications.Towards this purpose, sonobuoys are among the most capable sonar systems used in underwater environments.Sonobuoys are used to detect and track underwater objects emitting sounds.Recently GPS receivers have been integrated to sonobuoy systems to provide accurate information about sonobuoys positions.An accurate knowledge of geographic positions of deployed sonobuoys is critical for the conduct of antisubmarine warfare (ASW) operations and detected target localization.It enables processing array of GPS sonobuoys thus improving the target tracking accuracy.Considering that sonobuoy positions are accurately known, the main factors influencing the operation of sonobuoys would be the interference sources and background noise.professional supervision, critical discussions and immeasurable contributions.I would
