Ultra wide band radar has high range resolution capability, when UWB signals interact with target, and the responses of target are composed of many separate scattering centers.

超宽带雷达具有高分辩能力，它探测到复杂目标时，目标总的电磁散射是多散射中心的合成，回波信号不同于普通的窄带雷达回波。

The equivalent wide pulse (EWP) long coherent integrated technique with range resolution capability is proposed which can overcome range migration in a low observable target detector.

提出一种宽脉冲等效法，在不降低距离分辨率的前提下可克服雷达多个脉冲回波积累检测时距离走动的影响。

The sensors provide less range, less resolution and less collection capability than existing intelligence gathering aircraft, he said.

他说，同现有的情报侦察飞机相比，“全球鹰”无人机传感器范围小，分辨率低，搜集能力差。
