一种提高奇偶交错体积阵处理速度的分解方法

摘要

针对奇偶交错体积阵无法使用整齐布阵的快速处理方法造成计算量成倍增加的问题，文章详细分析了奇偶交错体积阵的处理过程，提出将奇偶交错体积阵按奇数号阵元和偶数号阵元进行分解，重新组合形成两个新的体积阵，然后分别对两个体积阵使用整齐布阵的快速处理方法，最后对两阵处理结果进行加权组合得最终结果，从而大大提高了奇偶交错体积阵的处理速度。通过仿真数据处理证明该方法的结果与直接计算的结果完全重合，但是处理速度远远大于直接计算的速度。%After analyzing the processing of the odd‐even staggered volume array in detail ,this paper proposes a method to solve the problem that the fast methods of the tidy volume arrays can not be used to deal with the odd ‐even staggered volume arrays so that the calculation increases greatly .This method decomposes the odd‐even staggered volume array to two new arrays ,one is composed of the odd elements of the old array ,another is composed of the even elements ,then the fast methods of the tidy volume arrays are used to calculate the beam‐forming of the two new arrays ,finally the two results are composed together .This method im‐proves the processing speed greatly .Through dealing with the simulation experimental data ,it is proved that the result of this meth‐od is the same with the result of common method ,but the speed is greatly faster .
