频率步进雷达是一种距离高分辨率雷达，运动补偿是其实现距离高分辨的关键。

Frequency stepped radar is a high range resolution radar, and motion compensation is the key technique to realize high resolution of range.

在远距离通讯和高分辨率雷达的应用中，要求天线具有高增益，反射面天线是使用最广泛的高增益天线。

High gain antenna is required in the long distance communications and high resolution radar applications in which reflector antenna is the most widely used one.
