Embodiment Construction

[0075] The present invention is described in detail below in conjunction with accompanying drawing:

[0076] In this embodiment, Hi-Target HD310 single-beam sounder is used to detect the inaccuracy of sounding, and three technical indicators of sound source level, resolution and beam angle are measured at the same time.

[0077] Sounding inaccuracy detection, including (1) static stability test of inner coincidence accuracy, (2) dynamic navigation test of inner coincidence accuracy, (3) static stability test of outer coincidence accuracy, (4) dynamic navigation test of outer coincidence accuracy;

[0078] (1) Static stability test of internal coincidence precision

[0079] Place the transducer of a single-beam echo sounder at a water depth greater than 5 meters,

[0080] First conduct sound velocity measurement, and input the edited sound velocity profile file into the single-beam echo sounder,

[0081] During the test, the single-beam echo sounder has been powered on contin...

Abstract

The invention discloses a detection method of a single-wave-beam depth sounder. The detection method comprises depth sounding inaccuracy detection, and particularly comprises the following steps of: (1) performing inner coincidence precision static stability testing; (2) performing inner coincidence precision dynamic navigation testing; (3) performing outer coincidence precision static stability testing; and (4) performing outer coincidence precision dynamic navigation testing. The detection method has high depth sounding accuracy, and the aim of detecting the reliability and the accuracy of the single-wave-beam depth sounder is fulfilled.

Description

technical field [0001] The invention relates to the technical field of marine surveying and mapping, in particular to a detection method for a single-beam depth sounder. Background technique [0002] The single-beam sounder is the main instrument in the fields of hydrographic survey, marine survey, national defense application and research, seabed topography and landform survey. In recent years, the single-beam sounder has been introduced and widely used in many domestic departments and units, and has played Huge effect. However, due to the lack of laboratory measurement and testing methods and the lack of unified standards, most single-beam echo sounders cannot perform standardized and effective testing and calibration, which seriously affects the accuracy and credibility of observation data. There are great quality risks. [0003] Therefore, the inventor wants to provide a practical and effective single-beam depth sounder detection method. Contents of the invention ...
