该论文针对光纤传感系统，深入研究随机信号的互相关函数和基于AR模型的功率谱估计，设计出具有事件发生检测功能的传感器信号处理算法。-The paper for the fiber optic sensor system, in-depth study of the cross-correlation function of random signal-based AR model spectrum estimation, designed with the incident detection s

在雷达、声纳、通信以及振动工程等领域中经常根据离散观测值（采样序列）对正弦信号的参数进行估计。采用复信号模型给信号分析和处理带来很大方便,因此文献中通常采用复正弦信号模型。-In radar, sonar, communications and vibration engineering and other fields are often based on discrete observations (sample sequence) of the sinusoidal signal para
