空管S模式二次雷达浅谈

Discussion of S Mode Secondary Surveillance Radar on ATC

随着民用航空事业的发展,传统A/C模式二次雷达难以满足空中交通管制(ATC)需求,S模式二次雷达正逐步取代A/C模式二次雷达。文章在比较分析两者的基础上重点阐述了S模式二次雷达的询问格式和应答格式,从而知道S模式二次雷达的特点及意义。最后介绍了S模式在其它领域的应用。

With the development of the civil aviation industry,the traditional A/C mode secondary radar is difficult to meet the needs of air traffic control（ATC）,the S mode secondary radar is gradually replacing the A/C mode secondary radar.Based on the comparative analysis inquiry format and response format of the secondary radar S mode were expounded,so as to know the characteristics and significance of S Mode secondary surveillance radar.Finally,use of S pattern in other fields was introduced.
