摘要
为了解决传统自适应旁瓣对消(ASLC,adaptive sidelobe cancellation)算法中构建相关矩阵所需大量复数运算问题,根据开环自适应旁瓣对消的基本原理和ASLC系统中相关矩阵和互相关向量的特点以及工程实现的要求,找到了一种快速构建相关矩阵的新算法,并详细说明和分析了该算法的运算流程和计算复杂度。经过理论仿真和DSP开发软件环境验证,该算法的计算复杂度明显小于传统算法。
In order to solve large amount of complex calculation for constructing the correlation matrix in traditional adaptive sidelobe cancellation(ASLC) algorithm,and based on the basic principles of open-loop adaptive sidelobe cancellation,the characteristics of correlation matrix and correlation vector in ASLC system,and the requirements of project implementation,a new fast algorithm for constructing the relevant matrix is proposed.The theoretical simulation and the verification by DSP development software indicate that,the computational complexity of the new algorithm is significantly less than that of the traditional algorithms.
