| 摘 要： | 多波束艏摇偏差校准是多波束校准的主要内容之一。针对目前多波束艏摇偏差参数不同航次校准其结果相差很大的问题,分析得出了风流压差是产生此差值的主要原因。为此在两种计算风流压差基础上,提出了计算艏摇偏差的改进算法,并利用实测数据进行了验证。验证结果表明：改进方法能够有效地计算出多波束的艏摇偏差,提高了多波束艏摇校准精度。

| Abstract: | The yaw-bias calibration is one of the multibeam calibrations in multibeam sounding. According to the obvious difference of yaw-bias in different voyage calibrations, the result of analysis shows that the leeway and drift angle is the primary reason. Based on two calculation methods of the leeway and drift angle, a modified method of acquiring the yaw-bias is provided in the paper. The test results show that the improved method could get better results of the yaw-bias of nultibeam, and increase the accuracy of the yaw-bias. |
