天线孔径 meaning in English

antenna aperture

Synthetic aperture radar ( sar ) , with " all weather " , day or night imaging capabilities , is an important role in the domination of earth observation
合成孔径雷达( sar )利用合成天线孔径技术可以产生更高空间分辨率的雷达图像。
Every phased - array rader needs thousands of phase shifters , which control the phase of radiator elements in the antenna aperture surface to scan beams fast
每部相控阵雷达需要上千个移相器,才能控制天线孔径面上各辐射单元的相位变化进而实现快速扫描。
The parameters that influence the single photon acquisition probability are the transmitter ' s tracking - pointing error , the far - field divergence angle , the link distance between transmitter and receiver and the receiver ' s antenna aperture
得到影响单光子捕获概率的主要参量是发射机的跟瞄误差、光束远场发散角、发射机和接收机的链路距离和接收机天线孔径。
Phase array radar can scan beams fast by controlling the phase of radiator elements in the antenna aperture surface , which shows many excellences such as agility , change celerity and multifunction . therefore , phase array radar is fit for the necessity of combat readiness
这种雷达通过电的方式控制天线孔径面上各辐射单元的相位变化，以实现波束的快速扫描，使其具有灵活、变化快速、多功能等优点，适应战备需要。
