Method for weak target detection in sea environment
In this study, a new method for sea surface target detection in low signal-to-clutter environment is proposed, which can not only reduce the computation amount but also suppress the sea clutter, static targets and noise. Firstly, the authors use a more general echo signal model, which is more matchi...
