自适应阵列处理能提高通信雷达等电子系统的抗干扰能力，因而获得了广泛的应用。许多重要的高速实时自适应阵列处理算法均需要采用一系列Ｇｉｖｅｎｓ旋转处理将输入数据矩阵变成三角阵。标准的Ｇｉｖｅｎｓ旋转包含开方运算，该运算是限制有关算法速度的一个重要因素。文中提出一种基于坐标旋转计算机技术的无开方Ｇｉｖｅｎｓ旋转处理方法，可以显著提高自适应算法的处理速度，并给出了这一方法的推导、Ｇｉｖｅｎｓ处理节点运算式和采用，这种方法的ＱＲ分解自适应阵并行处理算法的计算机模拟结果。
Adaptive array processing can improve the anti-interference ability of electronic systems such as communication radars, and has been widely used. Many important high-speed real-time adaptive array processing algorithms require a series of Givens rotation to transform the input data matrix into a triangular matrix. The standard Givens rotation contains an open-form operation, which is an important factor that limits the speed of the algorithm. In this paper, an open-form rotation-free rotation method based on the coordinate rotation computer technology is proposed, which can significantly improve the processing speed of the adaptive algorithm. The derivation of this method is given. Givens node operation formula and adoption, Computer simulation of QR decomposition adaptive array parallel processing algorithm.
