| 摘 要： | 波束角偏差是影响多波束系统测量精度的因素之一,严重时导致测量的海底地形成凸凹形状的伪地形。论述了波束角偏差产生的原因以及对多波束系统测量精度的影响,介绍了借用EM系列多波束系统配置的横向参数校准软件对波束角偏差进行校正的方法,经实际应用,该方法很好地校正了波束角偏差,提高了测量数据的精度。 |

| Abstract: | The beam angle offset is one of the factors that influences the measurement accuracy of the multibeam sounding system,and the severe cases can cause the measured submarice topography to form concave-envex pseudo terrain.The paper discusses the reason of beam angle offset and the influence to the measurement accuracy of the multibeam sounding system,and introduces the method that uses Roll-offset calibration software of EM series multibeam sounding systems to calibrate the beam angle offset.Through actual applications,the method nicely corrects beam angle offset,and raises the accuracy of the data measuring. |
| Keywords: | multibeam sounding system beam angle offset measure accuracy offset calibration |
