Concept Study and Designs of Radar Sensors for Maritime Surveillance and Near-Field Tsunami Early Warning

Kurzfassung

Off-shore detection of Tsunami waves is a critical component of an effective Tsunami early warning system (TEWS). Even more critical is the off-shore detection of local Tsunamis, namely Tsunamis that strike coastal areas within minutes from the triggering quake. In this paper we propose new concepts for near-field Tsunami early warning, based on innovative and up-to-date microwave remote sensing techniques. We particularly introduce the NESTRAD (NEar-Space Tsunami RADar) concept, which consists of a real aperture radar accommodated inside a stationary stratospheric airship providing continuous monitoring of tsunamigenic oceanic trenches.
