摘要分析了机载合成孔径雷达天线口径对成像处理的影响。 - 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。 - To improve this ability , a higher cross - range resolution is needed . an inverse synthetic aperture radar ( isar ) achieves high resolution in the cross - range dimension by taking advantage of the motion between radar and targets to synthesize the effect of a larger antenna aperture
逆合成孔径雷达( inversesyntheticapertureradar ,简称isar )信号处理对接收到的运动目标的回波信号进行相干处理,等价成一个大口径天线,很大程度上提高了方位向距离分辨力。
