Research on cross section of UHF radio wave scattering from surface waves on water

: Bragg scattering mechanism has been probed by a fully digital ultra-high-frequency (UHF) radar system. The system is based on studies of UHF radio wave (340 MHz) scattering from small-amplitude water waves. First-order radar cross section Doppler spectra have been measured. Com-paring them with theoretical models, good agreement has been found. The amplitude ratio (dB) of the cross section between incident and re ﬂ ected waves is 14.7 dB, and its deviation is 0.68%. The expectation of the normalized Doppler frequency shift of ﬁ rst-order peaks is 0.9850, and the deviation is 1.5%.
