摘要
研究了主分量分析方法发基本原理和实现方法,利用Delphi语言编写了应用软件,用某型坦克柴油机排气噪声信号进行了去噪应用的实例分析,验证了原理的有效性和程序设计的正确性,给出了关于数据矩阵构造,有效特征值选取这两个关键问题的几点指导性的建议。
Lucubrated the principle of denoising base on singular value decomposition,programmed internet applications used Delphi,the validity of algorithm and the correctness of software were validated by illustrational analysis used exhaust noise of tank diesel engine,put forward several instructive advices about the two key problems of data matrix construction and effective singular value choice.
