拖曳阵中的拖船干扰常常是限制目标的观测范围和检测性能的重要因素之一.在浅海环境中,由于拖船干扰存在严重的多途效应,采用传统的自适应干扰抵消方法,效果并不理想.为了抵消矢量拖曳阵的拖船干扰,利用矢量拖曳阵中振速通道正交于阵艏的分量对拖船干扰不敏感的特点,提出一种基于矢量阵的拖船干扰抵消算法.该算法抗多途干扰效果好,可以有效地抑制拖船干扰,实验数据处理结果验证了该算法的有效性,可望在实际的卢纳工程中得到应用.

To the towed sonar with a vector sensor line array, the interference of towed ship is an important factor that limits the sonar performance. Because of the severe multipath interference, the performance of the traditional adaptive interference canceling (AIC) is not satisfactory. For canceling the towed ship interference based vector sensor array, this paper provides an algorithm by taking the advantaged feature that the sound velocity vector component which is per-pendicular to the forward bearing isn't sensitive to the towed ship interference. The trial data processing result indicates the availability of this algorithm.
