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 a large number of complex arithmetic problems in constructing the correlation matrix in the traditional adaptive sidelobe cancellation (ASLC) algorithm, according to the basic principle of open-loop adaptive sidelobe cancellation and the correlation matrix and cross-correlation vector And the requirements of project implementation, we find a new algorithm to construct the correlation matrix quickly and describe and analyze the computational complexity and computational complexity of the algorithm in detail. After theoretical simulation and DSP development software environment verification, the computational complexity of the algorithm is obviously less than the traditional algorithm.
