【摘要】：潛艇目標(biāo)具有復(fù)雜的內(nèi)部結(jié)構(gòu),在對(duì)其進(jìn)行回波預(yù)報(bào)時(shí)需要考慮不同部位之間的遮擋效應(yīng)。選取某雙層艇的內(nèi)殼模型作為研究目標(biāo),首先利用三維建模軟件對(duì)其精確建模,然后利用網(wǎng)格劃分軟件對(duì)目標(biāo)建立兩組尺寸不同的板塊:大尺寸參考板塊和精細(xì)板塊,使用大尺寸參考板塊對(duì)精細(xì)板塊進(jìn)行遮擋判斷,可以通過(guò)減少遮擋判斷次數(shù),提高判斷速度。通過(guò)將改進(jìn)前后遮擋算法預(yù)報(bào)的目標(biāo)強(qiáng)度和運(yùn)算速度進(jìn)行對(duì)比,驗(yàn)證了改進(jìn)后算法的有效性和快速性,改進(jìn)后的遮擋算法更具有工程應(yīng)用價(jià)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.
