The data processing method study of sonar direction finding precision until marine dynamic measurement

提出白噪声多项式最优线性移动平滑滤波算法应用于分离声纳测向精度测量数据中的真实信号和随机噪声,并通过滤波方差比给出对随机误差的压缩程度;对声纳测向精度海上动态测量计算公式给出了完整的理论证明,并推导出更加精确的计算公式。试验结果表明,上述方法对声纳测向精度数据有效、适用。

Propose white noise multinomial most superior linearity migration smooth filter algorithm apply to, separate true signal and random noise of sonar direction finding measurement, and produces through the filter variance ratio to the compression degree of the random error; provides intact theory prove to sonar direction finding precision formula, and derives out the more accurate calculation formula. The test result indicates, method described above examines the sonar direction finding to the precision data effeco tivly, applicably.
