中文摘要：
本文利用线性正则变换域功率谱对单分量chirp信号进行了参数估计。作者首先推导了信号的LCT变换的统计特性,得到了信号的均值,相关函数并定义了线性正则变换域功率谱,进而导出了线性正则变换域中输入输出信号的相关函数与功率谱的关系,然后利用线性正则变换域功率谱对单分量chirp信号进行了参数估计。仿真结果表明该方法优于分数阶傅里叶变换域功率谱的参数估计。

Parameter estimation of single component chirp signal transform domain power spectrum. Firstly, by using the linear auto correlation function, and power spectrum of a signal in th dediced. Furthermore, relationship between the correlation func is studied based on the linear canonical canonical transform （LCT）, The mean, e linear canonical transform domain are tion and the main is obtained, Finally, parameter estimation for single component chirp on the LCT power spectrum. power spectrum in LCT dosignal is implemented based
