Radar sea clutter power modeling under the atmospheric duct propagation conditions?

摘要: 考虑近海面大气折射率垂直梯度的变化,采用曲面波频谱估计方法(CWSE)计算掠射角,并结合修正的GIT海表反射率模型和雷达距离方程对大气波导条件下雷达海杂波功率进行仿真,最后通过数值实验及与实测数据比较,验证了CWSE方法的可行性.

Abstract: Taking into account the variations of the refractivity gradient near the sea surface, We have used the curved wave spectral esti-mation (CWSE) technique to calculate the grazing angle. CWSE combined with the modified GIT reflectivity model and radar range equation, the radar sea clutter power modeling is performed under the atmospheric duct propagation conditions. Finally, the validation of CWSE is tested through numerical experiments and comparisons with the real measurement data.
