Abstract

To effectively extract the underwater laser target echo signal submerged in backscatter, a seawater backscatter filtering method based on an adaptive filtering algorithm is designed in this article. Firstly, the fundamental of the adaptive filtering algorithm is introduced, the LMS algorithm with simple iterative calculation and fast convergence is selected, and a new variable-step LMS algorithm is designed based on the traditional algorithm according to the signal characteristics. Then, to quantify the filtering effect, the SNR ratio at different distances is calculated and compared. The experimental simulation results indicate the effectiveness of the new algorithm applied to the backscattering cancellation.
