We study the feasability of ship wake detection in monostatic or bistatic radar images to get parameters such as the ship's heading and speed. We begin by describing the bistatic radar acquisition chain in the marine environment, in particular the electromagnetic wave scattering models applied to ocean surfaces and how to obtain an elevation map of the Kelvin ship wake. Then we describe a raw radar signal simulator able to tackle bistatic configurations, and we compare our results with data obtained from literature. The second part of the thesis is a study on ship wake detectability in radar images. First we consider the case of the so-called "dead water" wake, by benchmarking four typical reference chains. Then we study the detectability o...
