【摘要】：潛艇目標具有復雜的內部結構,在對其進行回波預報時需要考慮不同部位之間的遮擋效應。選取某雙層艇的內殼模型作為研究目標,首先利用三維建模軟件對其精確建模,然后利用網(wǎng)格劃分軟件對目標建立兩組尺寸不同的板塊:大尺寸參考板塊和精細板塊,使用大尺寸參考板塊對精細板塊進行遮擋判斷,可以通過減少遮擋判斷次數(shù),提高判斷速度。通過將改進前后遮擋算法預報的目標強度和運算速度進行對比,驗證了改進后算法的有效性和快速性,改進后的遮擋算法更具有工程應用價值。
[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.
