The second is that the fluctuation spectra of intrapulse and pulse-to-pulse are estimated respectively with modern spectra estimation approaches(maximum entropy and minimum cross—entropy).
第二个是采用现代谱估计技术（最大熵法，最小交叉熵法）分别对雷达发射信号脉内及脉间的起伏特性进行分析。
Based on the principle of minimum cross-entropy, diagnostic entropy in broad sense is applied to characterize the fault diagnostic process.
将故障熵的概念引申为广义故障熵，并结合最小互熵原理，用于阐述诊断推理过程。
