Abstract :
High-Frequency (HF) radars are operated in the 3-30 MHz frequency band and are known to cover ranges up to several hundred kilometers. Installed along the coastal regions at risk the radars can contribute to Tsunami Early Warning Systems. This paper describes the simulation of tsunami related signatures observed by HF surface wave radar at long ranges in case of a tsunami travelling towards the coast. The possible ocean surface current field changes due to a tsunami event are evaluated using the HF radar backscatter spectra.
