| 摘 要： | 本文介绍了对拖线阵海试数据进行窄带PIC处理的方法。用梯度算法、协方差矩阵递归直接求逆算法和RMGSEF算法进行了窄带PIC自适应处理。分析了学习曲线和输出平均功率波束图，进行了稳态计算和比较。表明RMGSEF算法是一种可用于多干扰波束、收敛快、抵消性能好、便于拖线阵声呐实现实时PIC处理的最好算法。 |

| Abstract: | This paper introduces the mathods processing towed-line array sea trial data with narrowband PIC, the gradient algorithm, direct inversion of the sample covariance matrix recursive algorithm and RMGSEF algorithm, analyzes the learning curves and the output mean power beam pattens, compares these algorithm with the steady state calculation results. It is shown that the Performance of RMGSEF algorithm is optimal at cancel and convergence, it is suitable for multiple interference beams and can make the towed-line array sonar to achieve real time processing. |
