Principal component analysic for field separation
The article contains different techniques of geophysical data processing by using soft ware Mathematica . Fields e paration is one of the mostimportant problem singe ophysical data interpretation. For potential fields, when there are observational data for the both the profile survey and are asurvey. The fields eparation becom esaprocess of estimation of low frequency component, i.e ., the regional anomaly, on the other hand, and high- frequency field component, i.e . the residual or local anomaly on the other hand .Principal components analys is for field separation provides immediate insight into the structure offield data and is applied for modeling the anomaly field that contains different bodies.The calculation process is realized by using the computer algebraic system (mathematica). The result of research is used in geophysical field separation for geophysical interpretation
