    摘要:

    结合多径散射理论和雷达成像原理,针对圆柱型固定顶油罐和浮动顶油罐的SAR图像的多径散射提出了一种预测模型, 该预测模型建立了多径散射机制引起的图像上的近似聚焦位置、强度与油罐、雷达相关参数的关系。同时,结合仿真实验和Terra-SAR图像验证了该模型的有效性,分析了油罐目标的多径特征,并针对Terra-SAR图像利用基于模型的方法有效提取了油罐目标的几何参. 结果和分析表明,该方法比传统的方法在精度、稳定性上均有所提高。

    Abstract:

    Combining scattering theory and principle of SAR, a novel prediction model is proposed based on the multi-path scattering characteristics in the SAR image of cylinder tanks, for both the fixed and the floating top styles. The model can provide the relationship between the geometry parameters of the tank, the SAR parameters , the approximation position, and the scatting strength of the bright region in the SAR image. The validity of the model is proved by analyzing the Terra-SAR data and simulation experiments. Furthermore, geometry extraction is successfully implemented on the Terra-SAR data. The results show that the model is better than traditional methods in precision and stability.
