Backscattered radar power

Fig. 8. Damping ratio, i.e., reduction of the backscattered radar power (in dB) induced by a PME slick, which was spread from ethanol, as a function of the Bragg wave-number. The measurements were performed at L-, S-. C-, X-, and >band using both W- and ////-polarisations (up- [tri-angles] and downwind [squares] look directions)...

Finally, the wind-dependence of the backscattered radar power (under different conditions. The results are shown in Figure 7, where the stars denote crrel values measured at a slick-free water surface and with rain, the circles denote values measured at a slick-covered water surface and with rain, the crosses denote values measured at a slick-... 

Fig. 7. Wind dependence of the relative backscattered radar power, areh measured under different conditions (x slick-free, no rain + slick-covered, no rain slick-free, with rain o slick-covered, with rain). Upper diagram W-polarization, lower diagram HV-polarisation...
