摘要
文章对微弱信号的相关检测原理和步骤进行了研究,给出了相关检测在数字域的快速实现算法。利用软件无线电思想设计了信号采集、数据处理平台,实现了较低信噪比信号的相关检测。
In this paper, the principle and process of weak signal detection based on the correlation are studied, and a fast algorithm of detection using correlation in the digital area A platform based on the theory of software defined radio is designed for signal acquisition processing, finally, the detection of low SNR signal is accomplished. theory of is given. and data
