| 摘 要： | 本文分析了T／R组件幅相不一致性对星载SAR雷达系统性能的影响，T／R组件不一致性对星载SAR雷达天线副瓣电平有一定的影响。由于天钱的融瓣电平是不同频率信号贡献的平均值，所以天线的副瓣电平的大小依赖平均T／R组件不一致性。

| Abstract: | In this paper,the effects on the performance of a SAR system due to the inconsistancy of the amplitudes and phases for the T/R modules .The results shows that the inconsistancy of the amplitudes and phases of T/R modules effect the sidelobe level of the antenna.Because the wide band signal can be expressed in terms of Fourier transform,so the sidelobe level of the antenna depends on the average inconsistancy of the amplitudes and phases of the T/R modules on the whole frequency band. |
