摘要
为解决高分辨率探雷声纳搜索水下目标的探测空间精确计算问题,将声纳探测波束视为刚体,利用波束的方向性函数和多波束成形特点,基于刚体坐标建立了高分辨率探雷声纳探测波束的表达模型;针对两类不同基阵结构的高频探雷声纳,分别依据刚体运动原理建立了精确的空间探测模型,实现了探测空间的精确表达;结合实际应用中声纳对水下固定目标的有效探测长度问题,明确了两类声纳的探测空间结构,分别采用解析和数值解法,对两类基阵的空间探测模型实现求解;为满足实际应用需要,提出并实现了一种声纳探测空间仿真三视图,可直观形象地表达整个探测空间,并用其验证了所建模型和求解方法的正确性。
In order to achieve the accurate calculation needed by the high-resolution mine detection sonar to search the volume of underwater targets, Sonar detecting beams were regarded as rigid body, multi-beam directivity function and multi-beam forming were in use, and based on rigid body coordination, detecting beam model of high-resolution mine detection sonar was established. For high frequency mine detection sonar of two different transducers, based on the movement principle of rigid body, precise volume detection model was set up respectively, and thus the accurate expression of volume detection was achieved. Associated with the practical sonar＇s effective detection length to underwater targets, volume detection structures of two types of sonars were determined. Adopting analytical and numerical solution respectively, the volume detection models of two types of transducers were solved. In order to meet the actual needs, simulation 3-D view of sonar volume detection was put forward and realized so that the entire detection volume could be expressed directly and vividly by which the established model and the solution method were proved to be correct.
