2, according to shallow point and dell distribution situation, the initial side for sweeping the traversing side of shallow tablet and pushing away is determined by principle from shallow to deep
To arrival slitting sideline flyback one time again, then again into pass, i.e., same depth round trip is swept shallow.
3, sweep it is shallow during if to sweep shallow tablet single-ended larger by resistance, and cause to sweep shallow tablet rotational steps larger
When, should suitably it reduce into pass distance.
The transverse moving speed for sweeping shallow tablet should be controlled when 4, sweeping shallow, is preferably controlled in 0.5m/s or so, and keeps transverse moving speed
Uniformly.The transverse moving speed for sweeping shallow tablet is unsuitable too fast, to prevent from sweeping shallow tablet rotation and break away.
Self-test measures：It is detected by mapping to sweeping shallow effect.
Complete all shallow regions sweep it is shallow after, need to be detected by mapping to sweeping shallow effect.Detecting instrument be GPS and
Sounding instrument, plane positioning are measured using GPS, and underwater topography preferably uses multibeam echosounder to carry out sweeping survey.
Water-level observation is synchronous with water-depth measurement when field operation operation carries out, and is carried out at interior industry data after completing whole field process
