Development of a high-frequency surface-wave radar cross section model for icebergs [PDF]

, 2016
In this thesis, the first-order radar cross section (RCS) of an iceberg is derived and simulated. This analysis takes place in the context of a monostatic high frequency surface wave radar with a vertical dipole source that is driven by a pulsed ...

High-Resolution Sea Surface Target Detection Using Bi-Frequency High-Frequency Surface Wave Radar

Remote Sensing
The monitoring of the sea surface, whether it is the state of the sea or the position of targets (ships), is an up-to-date research topic. In order to determine localization parameters of ships, we propose a high-resolution algorithm for primary signal ...
