MATLAB-based source code for weak signal extraction, detection, and analysis. The implementation first computes key statistical parameters including mean, mean square value, variance, frequency spectrum, and power spectral density of input signals to identify useful signal components. Subsequently, it extracts target signals and calculates their statistical properties (mean, mean square value, variance, probability density) along with spectral characteristics (frequency spectrum and power spectral density), accompanied by visualization of corresponding curves using MATLAB's plotting functions.
