Technical Needs and Challenges in Harbor Surveillance
High frequency sonar applications are not a new concept. Navies of the world have been using high frequency sonar to seek out mines for the past sixty years. More recently however, a growing imperative to counter terrorist threats to harbors and coastal areas has created the need for a new range of high frequency sonar products, designed to detect and track specific surface and underwater targets such as divers, swimmers and water vehicles. As a consequence, COTS vendors of acquisition products have been forced to re-examine, and in some cases redesign, existing technical solutions to cope with the very demanding requirements of these applications. Click on the attached white paper to read the newest approaches to acquire and process high frequency sonar signals and the benefits over older traditional approaches.
