The excitation polarization effect exists in the underwater detection of weak electric fish.In this thesis,based on the underwater positioning and detection method of weak electric fish,the optimization research is carried out with the help of the excited polarization method in geology.Analyze the experimental results to observe the effect of the extended experiment;on the other hand,starting from the variable frequency IP method,the eigenvalues of the two groups of frequencies are connected with the induced polarization effect.The main contents of this article include:1.Based on the underwater detection and positioning method of weak electric fish,a feasible extension experiment is proposed,a detection and positioning model is constructed,and an underwater active electric field positioning system is designed,developed and integrated.2.A detection method optimization experiment based on the DC IP method is designed,which can stimulate the excitation polarization effect of the measured object to the greatest extent,and is convenient to observe the detection object of small target in the laboratory.The experimental objects are copper cubes,copper cylinders,aluminum cubes,aluminum cylinders,and plastic cylinders,and an error analysis experiment is carried out,including time error and position error.According to the results of the error experimental analysis,this thesis designs the transient distance characteristic experiment and the contact excited polarization experiment,and further analyzes the experimental data.Different objects make a difference.3.According to the excitation polarization effect caused by two excitation signals with different frequencies,the detection method optimization experiment based on the variable frequency IP method is designed and carried out in this thesis.The frequency difference between the two excitation signals is required to be large,and the detection efficiency is high.on direct current.Copper cubes,copper cylinders,aluminum cubes,aluminum cylinders,iron cubes,iron cylinders,and plastic cylinders were used as the target objects of the experiment.The above eigenvalues analyze and process the experimental data,and innovatively apply the geological IP method to underwater detection.
