autocorrelation detection meaning in English

自相关检测

Two detection methods of chirp signals are presented in the dissertation : the cyclic autocorrelation detection method and the correlation detection method of cyclic autocorrelation function . it is shown that the two methods both have an excellent performance of blind detection . the performance analyses of the two detection methods are both carried out for additive noise or multiplicative noise , and the output signal - to - noise ratio ( snr ) expressions of the two methods are also derived
通过研究提出了两种线性调频信号的检测方法?基于循环自相关函数包络的检测方法和基于循环自相关函数的相关函数包络的检测方法，两种方法均可实现信号的盲检测，有良好的检测性能，文中还分析了加性噪声及存在乘性和加性噪声情况下两种检测方法的性能，推导出了输出信噪比公式。
