17306 该文构造了一种新的压缩变换(CT)函数，分析了该函数在零点附近的近线性，推导了任意随机变量经该函数变换后的2阶矩有界，证明了函数变换前后LFM信号的初始频率和调频斜率信息不变。 The paper constructs a new Compress Transform (CT) function, analyzes the approximate linearity of thefunction near the zero point, derives that the second-order moments are bounded after the proposedtransformation for any random variable, and proves that the initial frequency and frequency modulation slopeinformation of an LFM signal are unchanged after the transformation.
17307 将经过函数变换后的信号进行分数阶傅里叶变换(FrFT)，根据FrFT域中峰值坐标和信号参数的关系，寻找变换域中的峰值点，实现信号参数的估计。 According to the relationship betweenthe peak coordinates and the signal parameters in the FrFT domain, the peak point in the transform domain islocated and the signal parameters estimates can be obtained.

This method is simple and robust. Moreover, it does not require the prior information of the impulsive noise.
17309 针对循环相关熵谱估计循环周期图检测(CPD)算法存在计算效率低、频谱分辨率低和易产生“频谱泄漏”的问题，该文提出一种循环相关熵谱估计的Correntrogram算法。 A high computationally efficient algorithm for cyclic correntropy spectral analysis is presented whichis named as Correntrogram algorithm. Correntrogram algorithm overcomes the problems of Cyclic Periodogram Detection (CPD) method, such as high computational cost, low resolution and spectrum leakage.
17310 Correntrogram算法借鉴Wigner-Ville 分布(WVD)时频分辨率高的优势，将WVD算法中瞬时自相关函数替换为时变自相关熵函数，即可得到一种循环相关熵谱密度估计算法，称为Correntrogram。 Correntrogram utilizes the advantages of Wigner-Ville Distribution (WVD) which has high time frequencyresolution. By replacing the time-varying autocorrelation function with the time-varying auto-correntropyfunction in the WVD algorithm, the cyclic auto-correntropy spectral density estimation algorithm can berealized.
17311 首先计算信号的时变自相关熵函数矩阵，再计算时变自相关熵函数矩阵各行的FFT，得到循环自相关熵函数矩阵，最后计算循环自相关熵函数矩阵各列的FFT，得到循环相关熵谱密度。 First, the time-varying auto-correntropy function matrix of the signal is calculated, and then the FastFourier Transform (FFT) of each row of the time-varying auto-correntropy function matrix is computed to getthe cyclic auto-correntropy function matrix. Finally, the FFT of each column of the cyclic auto-correntropyfunction matrix is calculated to get the cyclic auto-correntropy spectral density function.
17312 通过仿真调幅信号的处理结果证明：Correntrogram算法有效提高了循环相关熵谱估计效率，避免了“频谱泄漏”，提高了频谱分辨率，该算法程序运行可靠。 The validity of theproposed estimator is demonstrated on a simulative amplitude modulation signal. The simulative result showsthat not only the proposed estimator is computationally efficient, but also has high frequency resolution andovercomes the spectrum leakage. The performance of Correntrogram is better than that of CPD method.
