基于chebyshev的水声信号分析，有均匀线阵的CRB曲线，包括脚本文件和函数文件形式，包括面积、周长、矩形度、伸长度，现代信号处理中谱估计在matlab中的使用，借鉴了主成分分析算法（PCA），基于分段非线性权重值的Pso算法。- Based chebyshev underwater acoustic signal analysis, There ULA CRB curve, Including scr ipt files and function files in the form, Including the area, perimeter, rectangular, elongation, Modern signal processing used in the spectral estimation in matlab, It draws on principal component analysis algorithm (PCA), Based on piecewise nonlinear weight value Pso algorithm.
