Analysis of beam sharpening effectiveness in broadband radar on inland waters

The paper presents results of the research on beam sharpening effect in inland waters. The idea of the research was to verify influence of beam sharpening on range and bearing discrimination in real environment. Research scenario assumes analysing the screen correlated with distance between targets, which allows examining real efficiency of beam sharpening process. The research set consist of SIMRAD 4G radar connected to processing computer. The area for the research covers inland waters near Szczecin. The new built RIS system includes also broadband antennas, thus the research has not only scientific, but also utilitarian background. The results presented in the paper will allow determining usefulness of broadband radar with beam sharpening effect for navigation, monitoring and tracking purposes.
