摘要
二次雷达(SSR)系统工作过程中出现了混扰、窜扰等内部干扰以及应答机占据等严重的问题,使得它的性能大大降低。本文在对这些问题进行分析之后,根据系统工作原理采用了适当的信号设计方式来减少这些干扰,最后从统计的角度定量分析了系统的性能。
There exist some problems in the operation of a Secondary Surveillance Radar(SSR)system,such as internal interference and occupancy of transponder,which will greatly deteriorate the performance of the system.In this paper ,after analyzing these problems ,new idea about signal design is adopted to suppress or reduce the interference.Finally,the performance of system is analyzed quantitatively using statistic method.
