摘　　要：为研究声阵列有关理论,解决弹载声阵列定位问题,分析了声阵列定位的本质原理,研究了声阵列定向和定距原理,推导了定距和定向之间的关系,为弹载阵列阵型选择提供了理论依据.指出了声阵列不能精确定距的根本原因,给出了弹载声阵列阵型设计理论,提出了运动声阵列三角定位法.得到了声阵列定距精度与定向精度之间的定性关系.结果表明,平面四方形阵列适合弹载,运动声阵列三角定位法是有效的.To research theories of acoustic array and solve the problem of localization of missileborne acoustic array, the direction and fix distance principle of acoustic array was studied. The relation of direction and fix distance of acoustic array was derived, which provided theoretical rules for selecting the missile-borne acoustic array architecture. The reason why the acoustic array can＇t precisely localize the target was pointed out. The design principle of missile-borne acoustic array architecture as well as triangle localization algorithm of moving acoustic array was proposed. The qualitative relation of direction and fix distance accuracy of acoustic array was gained. Planar square array is suited to missile-borne. The simulation proves that triangle localization al- gorithm of moving acoustic array is effective.
