多径效应及其对二次警戒雷达的干扰影响

Multipath and interference effects in secondary surveillance radar systems

在航空交通管制(ATC)方面,二次警戒雷达(SSR)较之一次雷达有许多优点,且有较好的性能/价格比。由于二次雷达在航管方面的应用愈来愈多,二次雷达的一些系统问题也就表现得较为突出了。本文讨论了多径和互扰的一些问题,并提出了相应的解决方法。

Secondary surveillance radar (SSR) offers many advantages for air traffic control (ATC) compared to normal (or primary) radar including substantially lower cost and improved performance. Because of the increasing reliance being placed on SSR by ATC a number of the system problems associated with, SSR are becoming less casily tolerated. The Paper discusses these problems, which mainly arise from multipath and mutual interference effects, and proposes solutions.
