| 摘 要： | 首先提出了一种经济而有效的仅改变激励相位的新方法来补偿ＳＡＲ天线功率方向图误差；其次讨论了ＳＡＲ天线在温度载荷作用下的特定的“缓慢变化”的系统变形；然后给出了一些算例以验证方法的有效性；最后给出了一些重要结论。

| Abstract: | A Cost effective,phase only adjustment technique to compensate for any error in SAR antenna power pattern is first presented,secondly,the particular "slowly varying systematic distortions"of SAR antenna subjected to thermal loads are discussed,and then some examples are taken to test the validity of the compensation technique,finally,some important conclusions are given in this paper. |
