Abstract :
Deals with preliminary results of the Joint US/Russia Internal Wave Remote Sensing Experiment (PreCHERI). The airborne radiometric (RM) complex and side-looking real aperture radar (RAR) are briefly described. The algorithms of sea surface temperature and surface wind restoration from RM data are outlined. The results of reconstruction are compared with true surface data. The standard deviation for wind direction is ΔΦ=5.3°(for wind speed Δv=0.43 m/s; and for temperature ΔT=0.38 degC). The comparison of RH data with RAR pictures shows a good agreement of backscatter in VV-polarization with the value of polarizational anisotropy in RM channels. It is concluded that combined analysis of RM and RAR data enables significantly improved algorithms to be developed for ocean remote monitoring
