【摘要】 阵型的选择是声音目标被动定位的关键技术之一。讨论和分析了基于四元平面十字阵的声音目标被动定位原理;利用目标与基阵平台分布在不同平面的特点,研究了采用简单的平面阵实现目标的三维定位,简化了布阵的复杂性。并针对基于四元平面十字阵的声音目标被动定位算法,分析了奇异值产生的原因,以及水平方位角、垂直俯仰角、时延估计精度、目标距离、基阵尺寸等因素对奇异值产生的影响。更多还原

【Abstract】 Array design is one of the key technologies of passive acoustic localization for the acoustic target.In this paper,the direction estimation technology of the acoustic target based on 4-element cross array is studied.According to the characteristic that the target and the array are in the different planes,the three-dimension localization method of the target is approached.By the use of this method,the structure of the array is simplified.During the process of computer simulation,the singular value and its cause are discussed.更多还原
