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 presents a Gram-Schmidt cascaded preprocessor that can be used to de-correlate the received signals of each array element of the adaptive array. This paper discusses and studies the principle, characteristics and circuit design of the preprocessor, and proposes a set of adaptive loop debugging method. The Howells-Applebaum adaptive loop is used here to implement the preprocessor unit circuit, and a ternary array adaptive quadrature preprocessor is designed and implemented.
