Prediction of Aeromagnetic System based on Digital Filters by MATLAB and Oasis Montaj Software
Authors: , ,
Abstract: This paper presents the applications of digital filters for prediction of aeromagnetic data signal processing. These data are collected by air graft and digitize using Oasis montaj software. Digital filters are applied to predict the hidden anomalies by eliminate noises and unknown frequencies. these used filters are: gaussian low/high, smoothing, edges of the anomalies in subsurface, derivative and analytical signals. they can be obtained using Potensoft code and Oasis Montaj Software. potensoft are based on MATLAB toolbox of processing, modeling and mapping of aeromagnetic data. Results indicate that Oasis montaj is peter than potensoft. These is due to Oasis montaj has predicted with high resolution and easily to determine anomalies locations and dimensions. Also, gaussian low pass filter give best results and indicate accurate anomalies level. Upwards continuation filters indicate best results for level anomalies. Introduce new derivative technique is useful in edge detection.
