Abstract

Ku band TCR receiver is designed and developed for GEOSAT applications of Indian space program. The receiver has been designed and implemented on modular based approach. Major modules are RF front end module, IF, LO and baseband .The paper discusses the design aspects of each module highlighting the design challenges at Ku band. The integrated characterization has been discussed with the receiver performance over various qualification test phases. The receiver incorporates synthesizer based Local oscillator design which has the advantage of no tuning elements and also gives the flexibility of setting the frequency as per the mission requirements at ground or tuning the receiver over 500MHz, allowing it to cater to in-orbit programmability requirement. The receiver has a command threshold of -110dBm and ranging threshold of -105dBm.The specifications, tests and the results are presented in detail. The developed receiver operates over 12.75–13.25 GHz band .The receiver is qualified for space use.

ku波段卫星遥控测距接收机的设计与实现

Ku波段TCR接收机是为印度空间计划的地球卫星卫星应用而设计和研制的。该接收机采用模块化设计方法进行设计和实现。主要模块有射频前端模块、中频模块、本端模块和基带模块，本文讨论了每个模块的设计方面，重点介绍了Ku波段的设计挑战。在不同的鉴定测试阶段讨论了接收机的综合性能。接收机结合了基于合成器的本地振荡器设计，该设计具有无调谐元件的优点，并且还提供了根据地面任务要求设置频率的灵活性，或将接收机调谐到500MHz以上，使其能够满足在轨可编程性要求。接收端命令门限为-110dBm，测距门限为-105dBm。详细介绍了该系统的性能指标、试验结果和测试结果。研制的接收机工作在12.75 ~ 13.25 GHz频段，满足空间使用要求。
