摘要：

A series of circle flights have been carried out over the wind driven sea, using the EMIRAD L-band polarimetric radiometer, described in [1]. Data are calibrated and corrected for aircraft attitude, and 360 degrees azimuth profiles are generated. The results show some variation over a full circle, typically about 1 K, and no clear, repeated azimuth signature from circle to circle is identified. Averaging reduces the variations, and frequency analysis of the profiles show an almost flat spectrum, which excludes a simple extrapolation of wind signatures, known at higher frequencies.
