摘要
拖线阵畸变以后需要进行阵形估计,传统上利用线阵上的多个航向传感器数据进行高阶多项式拟合方法面临着不易收敛的问题,且对航向传感器的精度要求高,本文采用二阶多项式进行拟合,对拟合算法进行仿真,仿真结果表明该方法能够较好跟踪阵形,对航向传感器的精度有较好的宽容性。
The array shape need to be estimated when towed array is not a straight line, the estimate method of using heading sensor data for a high order fitting curve facing difficulties of the divergence and the requirement of the accuracy of heading sensor, this paper proposed an second order polynomial to fit the shape. The result of the simulation indicated this method tracking the shape well, and has tolerance to the accuracy of heading sensor.
