摘要：

This paper presents an experiment description, dong with data examples, for ultrawideband radar measurements of low grazing angle forward scatter associated with a test target mounted above a wind disturbed sea surface. The measurement radar used sub-nanosecond transmit pulses (0.15 ns and 0.25 ns 3 dB pulse widths) at center frequencies of 9 and 4 GHz to achieve resolutions finer than 3 cm in the range dimension. This resolution was sufficient to fully resolve direct and multipath (both single and double bounce) contributions to the signal reflecting from a tower mounted retro reflector. The geometry produced a nominal 3 degree grazing angle for forward scatter. Dual frequency measurements For a wind disturbed ocean surface highlight changes in the magnitude and the location of the scatter components with time.
