利用倒谱技术对装备试验数据进行信号提取及应用的研究

摘要

对利用倒谱进行噪声中的信号提取技术进行了分析和研究。在装备试验数据的处理过程中，传统的处理方法经常假设噪声为加性的高斯白噪声，对抑制或消除乘性噪声没有有效的技术手段，但是在某些试验条件下，乘性噪声对信号的影响不能忽略，研究如何从受到乘性噪声污染的数据中提取有用信号，以应对实际任务中武器装备试验数据的事后处理及分析。%The author conducts analysis and discussions on extracting signal in noise with ceptrum technique.In the processing of equipment test data,with traditional processing method,we assume that the noise is additive white Gaussian noise,and have no effective technical approach to suppress or eliminate multiplicative noise.However,in some testing conditions,the influence of multiplicative noise is non-ignorable.Therefore,the study on how to extract useful signals from the data contamina-ted by multiplicative noise is of practical significance to post-processing and analysis of equipment test data.
