二次雷达S模式应答信号与ADS-B信号的甄别研究

Research on the discrimination between SSR mode S transponder signal and ADS-B signal

阐述了SSR的S模式应答信号与1090ES ADS-B系统的信号格式与特点,并对其进行了对比分析;针对这两种同频信号,提出了一种结合民航空管实际应用的区分方法。理论分析及仿真实验证明,该方法可较好地解决二次雷达S模式应答信号与ADS-B信号的甄别问题。

This paper describes the signal formats and characteristics between mode S transponder signal of SSR and 1090 ES ADS-B signal, on which comparative and analytic studies are also conducted. To distinguish these two signals of the same frequency, this paper proposes a method considering the practical application of civil aviation. By theoretical analysis and doing simulation experiment, this method proposeed in this paper can better solve the problem of distinguishing SSR mode S transponder signal and ADS-B signal.
