说明：  kurtogram是一种四阶谱分析工具，用于检测和表征信号中的非平稳性。可用于轴承的故障诊断(The kurtogram is a fourth-order spectral analysis tool elaborated for detecting and characterising nonstationarities in a signal. It relies on the assertion that each type of transient is associated with an optimal (frequency/frequency resolution) dyad (f ; Df) which maximises the kurtosis. The Fast Kurtogram computes the kurtogram over a grid that finely samples the (f ; Df) plane. Its complexity is on the order of N log N. This is the "plain vanilla" code used in paper: J. Antoni, Fast Computation of the Kurtogram for the Detection of Transient Faults, Mechanical Systems and Signal Processing, Volume 21, Issue 1, January 2007, Pages 108-124.)

在高频地波雷达探测系统中，接收系统的任务是将目标回波信号从很强的杂波和噪声干扰中提取出来，使得后续的目标信息提取得以进行。本课题从高频地波雷达接收机的工作原理出发，分析了高性能接收系统设计中的一些问题并提出了相应的解决方案。(In the high-frequency surface wave radar detection system, the receiving system of the target echo signal is extracted from the strong clutter and noise, making the subsequent target information extraction to be carried out. The working principle of the subject from the high-frequency surface wave radar receiver, this paper analyzes some of the problems in the design of high-performance receiver system and propose appropriate solutions.)
