TerraSAR-X is an Earth-observation satellite that travels around the planet in a polar orbit, and records X-band radar data about the planet using its active antenna.
TerraSAR-X是一颗地球观测卫星，环绕地球极地轨道飞行同时使用自身的有源天线记录X波段的雷达数据。
Coupled oscillators can realize desired phase distribution on the array by tunning natural frequencies of the elements, so it can be used in nonlinear active antenna array to control beam scanning.
耦合振荡器阵列可以通过调节单元的自由振荡频率实现阵面的特定相位分布，从而不用移相器实现有源天线阵波束电扫描。
