针对波浪破碎海况,采用考虑波浪破碎的KHCC03散射模式和散射计卫星遥感资料,对白冠覆盖率进行了反演研究,并得到了白冠覆盖率的反演公式.经检验,在10 m高度处风速取值为7 m/s—16 m/s时,利用文中给出的公式得到的白冠覆盖率反演结果与实测数据相比,优于以往其他计算公式的对应结果.这表明,利用散射计资料和波浪破碎的散射模式,可以反演白冠覆盖率.而且,这种方法不同于人们通常采用的被动遥感方法.

In this paper, the whitecap coverage is retrieved from the ERS-1 data and the KHCC03 scattering model which takes into account the effect of wave breaking, and a new whitecap coverage formula is obtained based on the retrieval results. The results calculated from this new formula of whitecap coverage have better agreement with the measured whitecap coverage than those obtained by some famous previous formula in the range of wind speed at 10 m height from 7 m/s to 16 m/s. This shows that it is feasible to retrieve whitecap coverage from scatterometer data and the scattering model including the effect of wave breaking. Moreover, this approach is different from those methods usually used in passive remote sensing.-
