基于双层涂敷模型的暗室静区精确计算方法
Calculation method for quiet zone of anechoic chamber based on double layer coating model
摘要
Abstract
To solve the problem that the efficiency of numerical method drops sharply at high frequen‐cy and the accuracy of high frequency algorithm is difficult to ensure in the quiet zone performance simulation of large scale anechoic chamber .A simulation method of double layer coating model based on shooting and bouncing ray was proposed .The model using real measurements was calculated and corrected .Double layer coating model simplified the cone wave absorbing materials ,and the shooting and bouncing ray (SBR) method effectively solved the curve reflection and far field accurately obtai‐ning problem .The simulation results indicate that this method can improve precision compared with the traditional method and can reduce time and memory .Both of the theoretical analysis and the simu‐lation results verified the validity and feasibility of the proposed method .关键词
