Comparison of the error correction methods of echo sounder
摘要
Abstract
Based on the on-site practice of measuring water depth with echo sounder, the relative merits and range of application of rod comparative measurement, water lump comparative measurement, and thermohaline correction in the error corrections of echo sounder were summarized. Rod comparative measurement is suitable for the depth of is less than 5 meters, and the accuracy is not reliable with water lump comparative measurement. The process and procedure of comparative measurement based on practical experience were discussed. This method measures the water depth by adjusting the sound velocity of echo sounder and reduces workload. Detector comparative measurement has practical significance in the error corrections of echo sounder for on-site use.关键词
