Abstract: The field measurement of the ice thickness and water depth distributions in a river, canal, or lake is one of the most important means of ascertaining and responding to an ice flood. A doublefrequency radar system using frequencies of 100 and 1500 MHz radars was developed in the present study. The system was used to measure the ice thickness and water depths with 87 and 89 points, respectively, in the high-latitude Mohe section of the Heilongjiang River. Comparison of the measurements with those obtained by traditional drill-hole methods verified the accuracy of the proposed double-frequency radar system. The system was further used to measure the distribution of the ice thickness and water depth over a distance of 0.5 km in the Longdao Wharf section of the Heilongjiang River. The results were used to develop appropriate ice flood prevention methods. The high accuracy of the proposed double-frequency radar system promises to significantly improve the efficiency of prototype observations of ice thickness and water depth.
