摘要
分析和比较了目前较为成熟的轨道长波长不平顺的检测方法 ,尽管随检测原理的不同 ,各国的轨检系统采用的处理方法相差很大 ,但其共同点是均离不开数字信号处理方法 ,从而保证系统有良好的幅频特性和相频特性。
This paper analyses and compares the inspection methods for long wave track irregularity which are successfully used in the track inspection systems at present.Due to difference of inspection principle,the processing approach used in the world has a big difference.However,they share the same characteristics of digital signal processing to guarantee good amplitude frequency and phase frequency feature of the system.
