Measurements of the dielectric properties of sea water at 1.43 GHz

摘要: Salinity and temperature of water surfaces estuaries bay regions are determined to accuracies 1 ppt salinity 0.3 kelvin surface temperature. L-band S-band radiometers used in combination as brightness detectors. The determination the versus salinity, with a parameter for 1.4 GHz, is performed capillary tube inserted into resonance cavity. Detailed analysis results indicates that measured values accurate better than 0.2 percent electric property epsilon' 0.4 epsilon''. calculated function kelvin. Thus it possible reduce data obtained two-frequency radiometer system accuracy range 5 40 ppt.
