海杂波背景下导弹目标的检测问题由于海杂波对检测的干扰而成为非常具有挑战的问题.本文通过利用多层快速多极子方法计算海面上方预设的通用导弹目标的有效雷达截面RCS,同时给出分数威尔斯特拉斯散射模型的简化形式,并利用其简化形式结合目标在海面投影面积计算海面RCS.最后,目标与其对应的海面RCS进行比较,得出雷达回波信杂比与入射角度、入射频率和极化方式的关系.结论可以帮助我们设计用于强海杂波背景下的导弹目标和其他类似目标检测的雷达系统.
The detection of missile targets in the background of sea clutter becomes a very challenging issue due to the interference of sea clutter with the detection.In this paper, by using the multi-layer fast multipole method, the effective radar cross-section RCS of the target of general purpose missiles above the sea surface is calculated , And at the same time, a simplified version of the fractional Willstra scattering model is given and the RCS of the sea surface is calculated by using the simplified form of the target in the projected area of the sea surface. Finally, the target is compared with its corresponding sea surface RCS, Than the relationship between incident angle, incident frequency and polarization mode.Conclusions can help us to design a radar system for missile targets and other similar target detection in the background of strong sea clutter.
