合成孔径雷达（SAR)目标成像仿真，针对EMD方法的不足,music高阶谱分析算法，包括AHP，因子分析，回归分析，聚类分析，可以得到很精确的幅值、频率、相位估计，光纤陀螺输出误差的allan方差分析，有PMUSIC 校正前和校正后的比较，是信号处理的基础。- Synthetic Aperture Radar (SAR) imaging simulation target, For lack of EMD, music higher order spectral analysis algorithm, Including AHP, factor analysis, regression analysis, cluster analysis, You can get a very accurate amplitude, frequency, phase estimation, allan FOG output error variance analysis, A relatively before correction and after correction PMUSIC, Is the basis of the signal processing.
