新型多频与传统单频无线电波透视仪的对比研究
Comparative study of new multi-frequency and conventional single-frequency radio wave perspective instruments
摘要
Abstract
In recent years,the research of multi-frequency radio wave perspective technology has made some progress,but at present,the commonly used radio wave perspective instrument mostly adopts a single frequency for detection,and the multi-frequency perspective detection instrument needs to be further developed and applied.By comprehensively comparing YDT-3 multi-frequency instrument and YDT-88 single-frequency instrument,it is helpful to understand the function of new equipment and its working effect.Comparison and analysis were carried out from equipment performance,data acquisition and test data.The comparison results show that the various technical indicators of the YDT-3 perspective instrument have met the design requirements,and with three frequency integration,the same experimental detection can save more than 60％time compared with single frequency equipment;In terms of detection data,the overall trend and attenuation pattern of the data collected by the YDT-3 perspective instrument are roughly the same as those of YDT-88,but the received signal near the measurement points affected by line interference is relatively stable.Therefore,it is believed that YDT-3 also has good detection effect and anti-interference ability.关键词
