This method applies to the wire antenna's rope slings influenced by focus forces with different strength, distance and direction, and it ensures fine shape to the antenna.
方法适用于不等大小、不等间距、不同方向集中荷载作用下的线天线悬吊索，可以保证天线施工后的成型良好。

The approach for enlargement of SAR patch mapping area by antenna beam scan is investigated, which serves for moderate fine-resolution mapping of medium-sized terrain patches.
研究通过天线波束扫描扩大SAR区域成像范围的方法，以适应较大区域中等分辨率成像的要求。
