【摘要】：潜艇目标具有复杂的内部结构,在对其进行回波预报时需要考虑不同部位之间的遮挡效应。选取某双层艇的内壳模型作为研究目标,首先利用三维建模软件对其精确建模,然后利用网格划分软件对目标建立两组尺寸不同的板块:大尺寸参考板块和精细板块,使用大尺寸参考板块对精细板块进行遮挡判断,可以通过减少遮挡判断次数,提高判断速度。通过将改进前后遮挡算法预报的目标强度和运算速度进行对比,验证了改进后算法的有效性和快速性,改进后的遮挡算法更具有工程应用价值。
[Abstract]:The submarine target has complex internal structure, so it is necessary to consider the occlusion effect between different parts in the echo prediction of submarine target. The inner shell model of a double-deck boat is selected as the research objective. Firstly, the accurate modeling is made by using three-dimensional modeling software, and then two groups of plates with different sizes are established by using the mesh division software: large reference plate and fine plate. The large size reference plate can be used to judge the block of fine plate, which can improve the judging speed by reducing the number of occlusion judgment. By comparing the target intensity and operation speed of the improved occlusion algorithm, the effectiveness and rapidity of the improved algorithm are verified. The improved occlusion algorithm has more engineering application value.
