| 摘 要： | CINRAD/SA雷达数字中频接收机改造后,取消了原先模拟接收机的中频环节的多个部件,在理论上系统的性能稳定性有明显的提高和改善,在维修上减少了接收机部件出错的概率。但实际改造完成后,雷达系统需要一个稳定的过程。在此过程期间雷达出现了诸如角码获取失败、不同仰角偶尔出现异常图片、系统相干性指标退化等问题,文章详细分析了出现这些问题的原因,并提出了相应解决方法。

| Abstract: | After rebuilding digital IF of CINRAD/SA radar,lots of units were canceled.Therefore,the stability of radar system was improved and error probability of receiver reduced in the maintenance.After practical rebuilding,radar system needs a stable process.During this process,the radar appeared several of problems,such as acquiring code failure,abnormal pictures in different elevation and system coherence degrading.This paper focuses on these problems and puts forward its treatment. |
