A Typhoon Wind-Field Retrieval Method for the Dual-Polarization SAR Imagery

Synthetic aperture radar (SAR) is widely used to detect sea surface wind. It has been found that the signals of co-polarization SAR tend to become saturated under high wind-speed conditions. Also, low signal-to-noise ratios of cross-polarization SAR have been observed under low wind-speed conditions. In this letter, a typhoon wind-field retrieval method is developed by compositing the wind speeds ...
