空管二次雷达S模式询问机目标捕获与监视实现方案

Target Capture and Surveillance Method for Mode S Air Traffic Control SSR Interrogator

提出了一种空管二次雷达S模式询问机捕获与监视空中S模式目标的工程实现方案。方案既考虑了S模式询问机的具体使用条件,又完全符合国际民航组织附件10的相关规定。采用S模式与A/C模式的兼容组合技术实现了过渡时期对空域目标的全面监视,采用自适应随机捕获技术实现空域中S模式目标的捕获和锁定,采用S模式多目标询问时序编排技术实现对同一波束内多个S模式目标的选址询问和监视。该方案已经在实际二次雷达S模式询问机研制过程中得以应用和验证,效果良好。

An engineering implementation method is proposed for air traffic control（ATC） system to capture and tail mode S airborne targets using secondary surveillance radar（SSR）. Either practical conditions of the mode S interrogator＇s employment or concemed standards of ICAO（International Civil Aviation Organization）Annexl0 are taken into consideration in this project. A combined and compatible technique is employed to surveille air- bome targets completely in transitional period. Self- adapted method of random capture is employed to capture and lock mode S aircraft. Multi - mode S targets in the same antenna beam are interrogated and tailed using time arrangement technique. The method has been applied and verified in a new developed mode S SSR interrogator, and the system runs well.
