| Abstract: | There is a higher need for improved time efficiency of underwater target detection and identification technology.A new method to fit spectrum is proposed.This method is quick and effective and we can extract continuous spectrum based on it.Part fitting and fixation fitting X-axis can improve time-efficiency.Simulation of MATLAB and CCS show that the method is feasible and effective. |
