In this paper, we derive the backscattering coefficient/forward propagation equation for frequency-modulated waves of high-frequency radar over the sea. Numerical simulations have been performed in order to compare the characteristics of a constant frequency and frequency-modulated electromagnetic wave in the function of sea state and index profile. From these simulations, we have drawn some conclusion...
In this paper, a new method is proposed to retrieve target reflectors heights for maritime surveillance applications. Multipath propagation over sea surface is used to retrieve the height information for each target reflectors. Firstly, radar raw data with multipath propagation are simulated. The back-scattered electric field from a marine scene is predicted with physical models for the environment...
