Abstract

Usage of the least squares and inversion methods are commonly applied to the geophysical data analysis. Solution of the theoretical anomalies of inclined sheet like bodies for the self-potential method were compared by writing a Fortran based computer program which is using simple iterative methods with damped least squares (MarquardtLevenberg) algorithm. As a result of theoretical model studies, model parameters have been reached with very little number of iterations at the small error limits. Applied Marquardt-Levenberg method damping factor has been carried out automatically in the program depending on converging and non-converging conditions. Depth, horizontal length and starting point ($𝑋_0$) parameters of the inclined sheet model were obtained within low error limits compared with the iteration methods for model and real field data.

Özet

En küçük kareler ve ters çözüm yöntemlerinin kullanımı jeofizik verianalizinde yaygın olarak uygulanmaktadır. Eğilimli tabaka benzericisimlerin kuramsal anomalilerinin doğal potansiyel yöntemi içinçözümü, basit yinelemeli yöntemler ve sönümlü en küçük kareler(Marquardt-Levenberg) yöntemi kullanılarak Fortran tabanlı birbilgisayar programı yazılarak karşılaştırılmıştır. Kuramsal modelçalışmaları sonucunda, küçük hata limitlerinde çok az sayıda yinelemeile model parametrelere ulaşılmıştır. Uygulanan Marquardt-Levenbergyöntemi sönümleme faktörü programda, yakınsak ve yakınsak olmayankoşullara bağlı olarak otomatik olarak gerçekleştirilmiştir. Eğimlilevha modelinin derinlik, yatay uzunluk ve başlangıç noktası ($𝑋_0$ ) parametreleri, model ve gerçek alan verileri için iterasyon yöntemleriile karşılaştırıldığında düşük hata sınırları içinde elde edilmiştir.
