In order to get better denoising result in laser interception, an improved wavelet threshold denoising algorithm was proposed. Through theoretical analysis and experimental verification, a series of simulation data were obtained. The results show that, compared with the traditional denoising algorithm, the speech signal-to-noise ratio after denoising is improved greatly. Denoising effect is obvious, signal waveform is smoother and distortion is less.
