Measurement and analysis of multi-frequency polarization backscattering of sea surfaces

A 71 SGHz multi-frequency (S, C , X, Ku-band) polarimetric scatterometer was used to study the EM backscattering from sea. The measurement methods in frequency and time domain and scattering data are present and analyzed according to frequency, polarization and angles of incidence. Correlations of data in frequency and time domain, scattering coefficient, statistical distribution of amplitude and Doppler spectrum are discussed.
