Problems solved by technology

At present, due to the lack of laboratory measurement and testing methods in China, and there is no unified standard, it is impossible to carry out standardized and effective verification, and only the method of on-site self-calibration or comparative measurement can be used, which seriously affects the reliability and accuracy of observation data.

Embodiment Construction

[0087] The present invention is described in detail below in conjunction with accompanying drawing:

[0088] This embodiment adopts the SeaBeam 1180 multi-beam depth sounder as the detected instrument, and the specific operation steps are as follows:

[0089] Multi-beam bathymetric system detection methods, including inner coincidence accuracy static stability test and dynamic navigation test, outer coincidence accuracy static stability test and dynamic navigation test,

[0090] Inner coincidence precision static stability test

[0091] Place the transducer at a position where the water depth is greater than 5 meters,

[0092] First conduct sound velocity measurement, and input the edited sound velocity profile file into the multi-beam sounding system,

[0093] During the test, the multi-beam bathymetry system was powered on continuously for more than 8 hours, and the water depth was compared every 15 minutes. The reference value was the first measured value. Depth standard...

Abstract

The invention discloses a detection method for a multi-beam sounding detection method. The detection method comprises an inner coincidence precision static stability test, a dynamic sailing test, an outer precision static stability test, a dynamic sailing test, and detection on a sound source level, a wave beam angle, resolution force, width sweeping ability and wave beam space. The method has important functions of measuring an ocean floor relief map and landform and ensuring the quality of sounding data of the multi-beam sounding system.

Description

technical field [0001] The invention relates to the technical field of marine surveying and mapping, in particular to a detection method for a multi-beam sounding system. Background technique [0002] The multi-beam bathymetry system can quickly and accurately obtain large-area seabed shape information, and provides a convenient and efficient means for seabed topographic map survey. At present, due to the lack of laboratory measurement and testing methods in China, and there is no unified standard, it is impossible to carry out standardized and effective verification. Only on-site self-calibration or comparative measurement can be used, which seriously affects the reliability and accuracy of observation data. Therefore, it is necessary to research and implement the detection method of the multi-beam sounding system to achieve the purpose of ensuring the sounding accuracy of the multi-beam sounding system. Contents of the invention [0003] The purpose of the present inven...
