摘要
通过对导弹发射车电磁计算数据进行不同姿态角和极化方式下的SAR成像处理,分析了不同俯仰角、方位角和极化方式下目标散射特性的变化规律;研究了不同极化通道目标峰值散射强度随方位角的变化关系,从计算数据中得到了目标的一些基本特性;进一步探讨了SAR目标计算数据在目标识别与分类中的应用前景。文中进行了大量的对比实验,归纳总结出一些有价值的结论,为更高精度的目标识别提供帮助。
The electromagnetic computation data under different pitch angles, azimuth angles and polarizations are processed using SAR imaging algorithm, and the varying relations between the target scattering characteristics and the pitch angle, azimuth angle and polarization, as well as the relations with different polarization channels for target scattering peaks, are studied. Some scattering characteristics of launch vehicle are acquired through computation data analysis. Further discussions about the application prospects of SAR computation data in target recognition and classification are presented. Several useful results are summarized through many comparison experiments, which are much useful for target recognition.
