用于干扰舰船目标的箔条云通常具有与舰船目标相近的尺寸和雷达散射截面积,这使得舰船与箔条云的识别成为一个非常有挑战性的问题。该文提出一种基于精细极化目标分解的识别方法。为了能够有效地识别舰船目标与箔条云,该文首先结合3种精细化散射模型,提出了一种基于精细散射模型的七成分分解方法。通过这种分解方法可以有效地刻画舰船目标的散射特性。为了将舰船与箔条云的极化特性进行有效的对比和区分,该文根据分解得到的散射成分贡献构造了一个稳健的散射贡献差特征。最后,通过将构造的散射贡献差与极化散射角结合,构造了新的特征矢量并利用支持向量机实现了最终的识别。实验利用仿真和实测的极化雷达数据对所提方法进行了验证,结果表明该方法优于现有的其他方法,并能够达到最高98%的正确识别率。
