冰水情一体化双频雷达测量系统
Double frequency radar system for ice thickness and water depth measurement
摘要
Abstract
For overcoming disadvantages of single frequency radar system,this study presents a new double frequency radar system with 100 MHz and 1500 MHz working frequency to measure water depth and ice thickness at the same time.A RTK system is used in this system to collect GPS coordinates of measuring points.To avoid interference,100 MHz and 1500 MHz radars work alternately and the working cycle is 15 ms.Consider that ice thickness and water depth change gradually,a correlation algorithm is used to track and measure horizon data to improve measuring accuracy.During the winter of 2015-2016,field survey was carried out at Longdao Wharf,Mohe Section of the Heilongjiang River where is the northernmost area in China.21 water depth and 19 ice thickness measuring points were used to compare radar system with traditional drill-hole method and then ice regime observation was carried out.This study provides a valuable reference for the future ice regime observation.关键词
