satellite transmitter

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。

Happy Feet has a microchip implanted in his leg and will also have an Argos Satellite transmitter attached to his back provided by New Zealand's Sirtrack.

“快乐的大脚”的腿上植入了微型芯片，背部也会放上新西兰Sirtrack公司提供的阿戈斯卫星跟踪传送器。

The difficulty of the mould forming and the knockout with thin-wall structure were solved. The thermal analysis strategy of satellite transmitter is worth much studying because satellite transmitter is a kind of complicated thin-wall structure component and its exact thermal analysis is difficult with many technical problems.

解决薄壁成型困难，薄壁带倒钩脱模困难等技术问题。卫星机载发射机属于薄壁复杂结构件，其整体精确热分析因为多种原因而无法进行，因此有必要对发射机热分析策略予以研究。
