| 摘 要： | 低频UWBSAR具有较大的方位向处理角,因此天线方向图沿方位向的变化不能忽略。本文给出SAR系统的时域处理模型,利用该模型分析天线方向图对系统性能的影响,然后给出天线方向图的校准算法,以及该算法的性能分析。最后通过计算机仿真,验证该算法的有效性,得到的仿真结果和理论分析相吻合。

| Abstract: | Because of large azimuth processing angle of low frequency ultra-wideband synthetic aperture radar, the azimuth variety of the antenna pattern cannot be neglected. In this paper, SAR system processing model based on time-domain is given, and how antenna pattern impacts on system performance is analyzed at first. Secondly, the calibration algorithm for the antenna pattern is proposed and the analysis of the algorithm is given. Finally, the computer simulation is used to verify this calibration algorithm, and result is agreed with the theory analysis. |
