自适应天线阵正交预处理器的研制

Implementation of Oirthogonalization Preprocessor in Adaptive Array

本文介绍了一种可用于自适应阵各阵元接收信号去相关的Gram-Schmidt级联预处理器。文中讨论和研究了这种预处理器的原理、特点及电路设计等问题,并提出了一套自适应环路的调试方法。这里采用了Howells-Applebaum自适应环来实现预处理器的单元电路,设计实现了三元阵自适应正交预处理器。

This paper introduces a Grain-Schmidt cascade orthogonalization preprocessor decor-relating the received signals in adaptive array. The theory and specialization and design of unit circuits of this preprocessor are studied. A series of method debugging the adaptive loop circuits is given and discussed. The Howells-Applebaum adaptive loop is used to realize the unit circuits and an actual orthogonalization preprocessor with three array elements is developped.
