High Frequency Surface Wave Radar (HFSWR) is one of the optimum solutions in order to monitor the Economic Exclusive Zone. Limited or no space is often provided by most countries to install the antennas of the receiving array onshore. Thus, placing them on independent buoys on the sea surface is a proposed solution as the available space is not limited. Unfortunately, this alternative solution also generates new problems that may alter the signals received by the antennas.

New reconfigurable compact antenna configurations and associated signal processing for improving the resolution of a surface wave radar.
The purpose of the thesis is first to do further studies on the problem of antennas placed on buoys, through measurements made in collaboration with IFREMER, ACTIMAR and the University of Hawaii and the NOAA.
This study will lead to a synthesis of the benefits / limitations of this configuration on buoys. The idea is then to study the configurations such as; buoys towed or placed on a barge, and their advantages / limitations respectively.
Finally, combining the benefits of various basic configurations of radar surface waves (on land, buoy, or towed barge) will lead to the definition of a Surface Wave Radar with better resolution.
My work is based on the research and development of a high-frequency surface wave radar placed on buoys on the sea surface. It consists of developing methods for improving the resolution of the radar using this new technology, based on a simulator developed during my thesis and based on experimentations made on a floating antenna in France and in the United States (Hawaii) with the collaboration of the University of Hawaii, the National Oceanic Atmospheric Administration, the ACTIMAR and IFREMER.
