Research on a New Denoising Algorithm for Geomagnetic Signals
Geomagnetic observation data is widely used.Due to the sensitivity of geomagnetic observation data to various environmental factors,the processing and utilization of geomagnetic data are seriously affected.Chaotic se-quences can provide certain randomness and nonlinear characteristics to help optimization algorithms better search for optimal solutions.The geomagnetic signal is the original signal that needs to be denoised.By using Chaos Ant Colony Algorithm to construct the objective function,geomagnetic signals can be optimized and denoised.The al-gorithm will gradually adjust the parameters and features of the signal by simulating ant colony behavior and guiding chaotic sequences based on the setting of the objective function,so as to achieve the purpose of reducing noise and extracting effective information.
