全极化沿航向干涉SAR系统参数优化设计

Optimization design for the fully polarimetric along-track interferometric SAR system parameters

为最大化全极化沿航向干涉合成孔径雷达(synthetic aperture radar,SAR)系统相对于单极化沿航向干涉SAR系统的运动目标检测优势,建立了一种以可测速区间长度之比为目标函数的优化模型,提出了相应的最优解求解方法。仿真实验结果表明,与模型最优解对应的参数设置充分利用了雷达系统的极化信息,最大化了全极化干涉系统在运动目标检测方面的优势。

To maximize the advantage of the fully polarimetric along-track interferometric synthetic aperture radar（SAR） system compared with the single polarimetric along-track interferometric SAR system,an optimization model in which the object function is the proportion of the detectable velocity length of the two interferometric SAR systems is constructed and the method to this optimization problem is proposed.The simulated results indicate that the solution of the optimization model makes the best of the polarization information and maximizes the advantages of the fully polarimetric along-track interferometric SAR system in the global moving target indication.
