摘要
在讨论了STMV(导向最小方差)波束形成算法原理的基础上,提出了STMV波束形成算法的逆QR(正交分解)分解SMI(采样矩阵求逆)实现方法,讨论了逆QR分解SMI算法的Systolic阵列并行实现结构,分析组成Systolic阵列的各PE(处理单元)单元的基本运算模块的实现,并研究了逆QR分解SMI算法基于Systolic阵列结构的FPGA(现场可编程门阵列)并行实现方法。
On the basis of discussing STMV(steered minimum variance)beam-forming algorithm principle,the implementation method of STMV beam-forming algorithm with inverse QR(orthogonal decomposition) into the SMI(sample matrix inversion)is proposed.The Systolic array parallel structure of inverse QR decomposition of the SMI algorithm has been discussed.The composition of Systolic array each PE(processing unit)basic operations module is analyzed.Inverse QR decomposition of the SMI algorithm is based on the Systolic array structure of the FPGA(field programmable gate array)parallel implementation method.
