Airborne Maritime Surveillance Radar, Volume 2

Post-war British ASV radars 1946–2000
Simon Watts

Description

Today, air-to-surface vessel (ASV) radars, or more generally maritime surveillance radars, are installed on maritime reconnaissance aircraft for long-range detection, tracking and classification of surface ships (ASuW—anti-surface warfare) and for hunting submarines (ASW—anti-submarine warfare). Such radars were first developed in the UK during WWII as part of the response to the threat to shipping from German U-Boats. This book describes the ASV radars developed in the UK after WWII (1946–2000) and used by the RAF for long-range maritime surveillance.

About Editors

Simon Watts graduated from the University of Oxford in 1971, obtained an MSc and DSC from the University of Birmingham in 1972 and 2013, respectively, and a PhD from the CNAA in 1987. He is author and co-author of more than 80 journal and conference papers, a book on sea clutter, and Airborne Maritime Surveillance Radar.
