| 摘 要： | 针对航管二次雷达地面询问机系统开场测试情况,讨论了一种基于航管二次雷达测试仪信号处理的抗汇叠、去异步干扰算法。该测试仪将接收到的询问信号通过包络检波和运算放大后,送到A/D卡进行数据采集,通过抗汇叠、去异步干扰信号处理算法,分离出各个询问信号,并对其进行测试、分析和判别。结果证明,该测试仪信号处理算法可分离出多部雷达的信号,在实际的工程中取得了较好的检测效果和应用。

| Abstract: | According to the testing circs of SSR asking machine in the open air,a processing arithmetic,which is based on SSR measuring instrument,with resisting mix and asynchronous interfering had been discussed.After demodulation and operation amplifying,the SSR asking signals were sent to A/D conversion equipment to obtain digital data.Then the SSR measuring instrument separated the asking signals with the resisting mix and asynchronous interfering arithmetic,and then tested,analyzed and distinguished the signals.... |
