An underwater terrain navigation method based on Bayesian estimation is proposed for autonomous underwater vehicle (AUV), according to the depths measured by multi-beam echo sounder (MBES). For the shortage of false peak increasing intensely at low characteristic area of this method, the Fisher criterion is introduced. This method effectively reduces the false peaks, enhances the discrimination of...
To overcome the sensor system problem of fault diagnosis and signal recovery for autonomous underwater vehicle (AUV), a method based on strong tracking filter (STF) theory and singer model of first order time correlation function was proposed. The STF-Singer model by combining the signal processing method and STF method dose not need the accurate mathematical model of the controlled plant, and it...
