The X-band magnitude of cross section per unit area sigma sub O at various grazing angles was measured using nanosecond radar techniques and sea-clutter generation in the NRL swimming pool. The sigma sub O curves for both horizontal and vertical polarization have been measured and fall near open-ocean observed values in the range of 8 degrees to 80 degrees. Below 8 degrees the open-ocean values are higher, and above 80 degrees they are lower. Some statistical properties of small-wave sea clutter are shown. Cross section sigma sub O as a function of wind velocity was measured. The combination of nanosecond radar techniques and the carefully controllable environment of the swimming pool permits unique measurements of properties of targets and sea clutter over water. Author
