周期微弱信号的检测与跟踪

Detection and Track of Weak Periodic Signals

本文以实验为依据,阐述了用单板机实现对周期微弱信号的检测、恢复和跟踪技术,重点讨论了如下内容: 1.提出了漏值取样,在此基础上对传统的多点数字平均技术加以改进,给出了更加有效、适应性更强的漏值多点数字平均。2.对周期未知信号的检测和恢复方法。3.对周期蠕动的微弱信号的检测、恢复和自适应跟踪技术。

This paper, based on experiments, describes the techniques of detecting, recovering and tracking weak periodic signals, which are implemented on a single-board computer. The following contents are discussed: 1. The method of missing sampling, that improves the classical method of multiple sampling averaging, and produces a more adaptable method of multiple sampling averaging based on missing sampling. 2. The method of detecting and recovering unknown weak signals. 3. The technique of detecting, recovering and adaptively tracking weak signals with periodic wriggles.
