基于卡尔曼滤波的水声信号线谱增强（英文）

发布时间：2022-10-15 20:28

　　To detect weak underwater acoustic signals radiated by submarines and other underwater equipment, an effective line spectrum enhancement algorithm based on Kalman filter and FFT processing is proposed. The proposed algorithm first determines the frequency components of the weak underwater signal and then filters the signal to enhance the line spectrum, thereby improving the signal-to-noise ratio（SNR）. This paper discussed two cases: one is a simulated signal consisting of a dual-frequency sinuso...
