摘 要：在没有 S 模式二次雷达的情况下，为进一步提升 ADS-B 地面站后端数据融汇系统和自动化系统数据融合的可靠性，使 ADS-B 的报文包含二次代码，通过在 ADS-B 站点增加询问发射功能，获取当前空域 S 模式应答机地址码，再控制询问发射机 UF5 点呼飞行器下发二次代码。验证结果表明，ADS-B 接收机发送的 ADS-B 报文有效地关联上正确二次代码，从而可以将询问发射机有效应用到无 S 模式二次雷达的 ADS-B 覆盖区域，有效提高该作用范围内 ADS-B 报文的二次代码挂码率。

Abstract: To make ADS-B message contain secondary code without S-mode secondary radar, so as to improve the reliability of data fusion between back-end data fusion system and automation system. Add the interrogation transmitting function at ADS-B station, obtain the address code of mode s transponder in the current airspace through ADS-B data, and then control the interrogation transmitter UF5 calling aircraft to send the secondary code. ADS-B message sent by ADS-B receiver is effectively associated with correct secondary code. The effective application of interrogation transmitter in ADS-B coverage area without S-mode secondary radar can effectively improve the secondary code hanging rate of ADS-B message within this range.
Keywords: ADS-B; S-mode interrogation signal; secondary code; BDS register
