雷达参数对SAR图像中Kelvin尾迹的影响

舰船尾迹的SAR成像受到船艇自身、海洋环境和SAR系统等多种因素的影响,其中起主要作用的是雷达参数的影响。文章重点对影响舰船Kelvin尾迹SAR成像的SAR系统参数进行了详细讨论和分析,其中包括极化方式、视向角、频率以及入射角对Kelvin尾迹的影响因素。给出了各种参数对尾迹成像的影响规律,通过此规律有助于下一步得出舰船尾迹的最佳观测条件。

Influence of Rada Parameters on Kelvin Wake in the SAR Image

Ship wake of SAR imaging by boat, ocean environment and the influence of many factors such as SAR system,which plays a main role is the effect of radar parameters. In this paper, the key to affect ship Kelvin wake the SAR systemparameters of SAR imaging had carried on the detailed discussion and analysis, including polarization modes, dependingon the angle, frequency, and incident angle of the influence factors of Kelvin wake. The influence law of various parame.ters on the trail imaging was given, it helped to obtain the best observation condition of the ship wake next.
