Abstract : Several case studies of radar sea clutter are presented which show that backscatter is received from ranges much beyond the predicted radar horizon. No definite explanation for this has been found but it is believed to be primarily due to over-the-horizon scatter propagation. It is proposed to restrict the sea clutter data analysis to about 25 nautical miles range from the radars studied in order to reduce the effects of changes in atmospheric propagation conditions. Radar video tape facilities and marine environmental sensors for wind, waves, and current are described. Methods are presented for spectrum analysis of radar sea clutter video stored on tape. If these prove successful, they ultimately can be applied operationally in real time. (Author)
