摘要
在深入分析波—流作用方程、海面雷达后向散射模型的基础上,建立了波—流作用产生的海面雷达后向散射系数扰动模型,并进行了与Alpers模型的对比数值试验,并对两模型的试验结果吻合度给出了统计分析。结果表明,模型计算的海面非均匀流场引起的雷达后向散射系数扰动与Alpers模型的结果相当一致,可以作为研究雷达对海面非均匀流场效应探测能力的一个数值分析模型进行应用。
Based on deeply analyzing wave-current interaction equations and radar backscattering model of ocean surface, it developed a calculating model of radar backscattering coefficient caused by wave-current interaction on ocean surface.Then the model is compared with the well known Alpers's model through numerical test on calculating radar backscattering coefficient perturbation caused by ocean surface non-even current fields.Furthermore it provided the statistical and analyzing results of the two models' coherence degree. The results show that the two models are coincident.Thus this paper's model can be regarded as a numerical model to study radar's ability for detecting ocean surface non-even current fields.
