| 针对单频雷达在冰厚和水深同时测量中的缺点，提出了以100 MHz和1500 MHz雷达为基础的冰水情一体化双频雷达测量系统，并通过RTK系统实时采集测点的经纬度坐标。该系统通过交替工作周期为15 ms的分时工作来避免不同频率雷达间的相互干扰，利用冰厚和水深综合探测时在时间上表现为相邻道号数据振幅稳定、渐变的特点，采用相关性层位追踪算法提高测量的准确性。在我国纬度最高的黑龙江漠河段，通过21个水深和19个冰厚测点与传统观测方法进行了对比验证，并通过原型观测应用支撑了黑龙江龙岛码头河段春季的防凌爆破。结果表明基于双频雷达的冰水情一体化系统可大幅提高冰水情野外原型观测的效率，为长河段的冰厚、水深测量提供新的手段。 |

| 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. |
