The arrival of components must been picked for the method of maximum entropy and cross power spectrum phase.
最大熵与互功率谱相位法就是首先求出组分波的波至点。
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。
