发射天线孔径
A direct mathematical expression for the relationship between the transmitter optics aperture and the satellite vibration amplitude has been derived. The assumption in the derived model is that the satellite communication system adapts on-off keying ( OOK) modulation and an APD as the detector.
从接收机的比特误码率与发射机的振动关系出发,采用OOK调制方式,以APD为光电探测器,推导得到了描述发射机天线口径与发射机振动关系的数学模型。
Space traveling wave tube ( TWT) is the core component of satellite transponder and spaceborne synthetic aperture radar transmitter, Therefore, it is knew as the "heart" of satellite communication systems.
空间行波管是星载转发器和星载合成孔径雷达发射机的核心部件,因此被誉为卫星通讯系统的心脏。
