摘要
随着测控系统的不断更新,设计实现兼容多种测控体制的应答机非常必要。介绍了S频段多模式、多功能、宽频段应答机的设计方案,论述了其中的关键技术和工作原理。该应答机在扩频模式和调相模式下具有测距、测速、解调遥控指令和发射遥测副载波的功能,相比以往的S频段应答机方案,具有电路简化、功能较多的特点,因而能适应多种测控工程。
With the continuous upgrade of TT＆C systems,it is necessary to design transponders compatible with multiple TT＆C systems. This paper presents an S - band multimode multifunctional broadband transponder,and demonstrates its key techniques and operation principle. The transponder is capable of ranging, velocity measurement, command instruction demodulation, and telemetry subcarrier transmitting, either in the mode of spread spectrum or PM. Compared with traditional S - band transponders, this one is featured by simplified circuits and multifunction, so it can be applied in many TT＆C projects.
