综合化S模式应答机设计

Design of Integrated Mode S Transponder

介绍了S模式航管应答机的特点,分析其应答延时指标,然后在给出综合化S模式应答机方案的同时对比了与传统独立端机的设计区别,指出A/C应答延时是综合化S模式应答机实现的关键技术。文中提出了压缩接收链路延时、改进波形算法与优化发射链路时序相结合的方法,解决了综合化通信导航识别设备中航管应答功能从传统A/C模式升级至S模式的关键问题。

This paper introduces the characteristics of mode S transponder,and then analyses reply delay.At the same time,the design of integrated mode S transponder is compared with that of the traditional standalone terminal. It is pointed out that reply delay in mode A/C is the key technology of mode S responder. A method is proposed to solve the key problem when the ATC transponder upgrade from traditional mode A/C to mode S in integrated communication,navigation and identification(ICNI) equipment,which method reduces delay of receive chain,improves waveform algorithm and optimizes sequence in the chain of emitter.
