Near zero grazing angle forward-scatter sea clutter measurement spectrum analysis

There is a lack of published experimental forward-scattering radar sea clutter data at very low (almost zero) grazing angle over the sea. This data is necessary to provide a fundamental understanding of the operating environment for the development of forward-scatter radar systems for maritime applications. Experimental data has therefore been recorded at frequencies of 7.5 GHz, 9.3 GHz, 24 GHz, and 37.5GHz using Forward Scatter Radar with static, medium gain antennas for low sea states 1–3. Results of clutter power spectral density measurements are presented and conclusions drawn from the results.
