基于kaiser窗的双谱线插值FFT谐波分析，结合PCA的尺度不变特征变换(SIFT)算法，采用了小波去噪的思想，使用混沌与分形分析的例程，阵列信号处理的高分辨率估计，一种流形学习算法（很好用）。- Dual-line interpolation FFT harmonic analysis kaiser windows, Combined with PCA scale invariant feature transform (SIFT) algorithm, Using wavelet denoising thought, Use Chaos and fractal analysis routines, High-resolution array signal processing estimates, A fluid manifold learning algorithm (good use).
