摘要
L波段雷达高空气象探测中,重放球是影响高空探测质量的因素之一,重放球操作及信号重叠问题一直困扰着高空气象观测员,是影响高空探测质量的难题。基于此,文章结合工作实践总结了一些重放球的操作经验和技巧,为更好的完成高空气象综合探测工作提供参考;其中对信号重叠问题做了重点分析,并提出具体解决方法:即通过调整施放探空仪频率的方法错开两探空仪回答器的发射频率,使L波段雷达只能接收与之对应频率的探空仪回答器发射的频率,此方法从根本上有效解决了重放球引起的信号重叠问题,并在实际工作中得到验证,效果良好;大大提高了高空气象探测业务质量。
In the L-band radar upper air meteorological observation,replay ball is one of the factors affecting the quality of upper air meteorological observation,upper air meteorological observer has been puzzled by replaying ball and signal overlapping,and it is also a difficult problem affecting the quality of upper air meteorological observation.Based on this and combined with working practice,this article summarizes some operating experiences and skills of replaying ball and provides a reference for complete the upper air meteorological comprehensive observation better.It focuses on analyzing the issue of overlapping signals,and puts forward specific solutions that is by adjusting the later radiosonde frequency to stagger frequencies of two radiosondes,so the L-band radar can only receive the corresponding radiosonde frequency.This method has fundamentally solved the signal overlapping problems caused by replay ball,and has been verified in working practice.The effect is good that greatly improves the quality of the upper air meteorological observation.
