摘要
本文介绍用乘积模型定义的局部平稳随机过程,乘积模型将局部平稳随机过程分成两部分,分别在时间域和频率域进行处理,并给出相应的偏度误差和统计误差。应用部分介绍局部平稳随机数据处理方法在改善潜地导弹在弹射时的振动环境和控制振动环境方面的经验。
In this paper, the local stationary random process (LSRP) defined by the product model is introduced. The product model divides the LSRP into two parts, then deals with them in time and frequency domains separately, and gives the bias and statistical errors correspondingly. In the application section, the practical experience of using the data-processing method of LSRP to improve and control the vibration environment of a submarine-to-surface missile being ejected is presented.
