摘　　要：介绍了一种新型的磁引信横向区域控制算法,即对每2个相邻抽样点的磁场矢量进行叉乘,用叉乘矢量结果与铅垂线夹角的三角函数值数列构成横向区域控制特征量,实现横向区域的准确控制。克服了以往磁引信采用磁场余弦单点计算最大值,而导致判断目标滞后甚至超出水雷打击范围的缺陷。A novel magnetic fuse breadthwise area control algorithm is introduced in this paper.The magnetic vectors of two adjacent samples are orthogonally multiplied.The trigonometric function series of cross angle between the above multiplied result and the perpendicular direction forms the breadthwise area control character value,which realizes the accurate control of the breadthwise area.The method overcomes the limitation of target determination delayed or even overrun from the mine attack area,which is introduced by the old method to compute the maximum value by the single magnetic cosine value.
