Abstract

A frequency domain method for the blind multi-inputs multi-outputs (MIMO) underwater deconvolution is developed to estimate the original acoustic channel from received signals on hydrophones only, with the low signal to noise ratio (SNR). The method is not influenced by a long impulse response order and sparse underwater acoustic channel in time domain. By inversing the blind deconvolution result, the origin MIMO channel impulse response can be obtained. The results based on simulation model of underwater acoustic field prove this work to be effective and efficient for blind estimation of the shallow-water acoustic channel.
