在探测、医疗等领域,对微弱信号检测准确性的要求非常高,但微弱信号不仅自身信号强度非常低,而且在传播的过程中,通常伴随一定的噪声和干扰,使检测工作要建立在盲源分离方法的基础上,极大的增加了微弱信号的检测难度。在此背景下,本文针对微弱信号检测的盲源分离方法和应用问题展开研究,为相关领域提升微弱信号的检测准确性提供参考。 In the fields of detection and medical treatment, the requirements for the detection accuracy of weak signals are very high. However, weak signals not only have very low signal strength but also usually carry some noise and interference during the propagation so that the detection work needs to be established in a blind Based on the source separation method, it greatly increases the detection difficulty of weak signals. In this context, this paper focuses on the blind source separation method and application of weak signal detection, and provides reference for improving the detection accuracy of weak signal in related fields.
