自适应数字波束形成的格式滤波算法

The Lattice Filter Algorithm for Adaptive Digital Beam Forming

从矢量空间分析的角度，分析了格式滤波算法在自适应波未形成中的应用，以空间正交化原理为基础，得到了一种新的递推型格式滤波算法，使格式滤波器的阶次降为原来的一半，从而较大地减少了算法的运算量以及简化了硬件结构。

With the theory of vector and space analysis, the paper studies the application of lattice filter algorithm in space domain:adaptive digital beam forming. With the new recursive at the basis of space orthogonalization, a new recursive lattice filter algorithm with half orders is presented so that the operation of the algorithm caculation and the hardware architecture are simplified apparently.
