Abstract
The errors of estimates of the size, depth, and magnetization of a local source of a simply shaped magnetic anomaly are studied by means of a comprehensive analysis of the magnetic survey performed at different altitudes. Numerical simulations show that the values of magnetic induction induced by the presence of a magnetic source measured at different altitudes provide a more accurate estimate of some parameters of this source than the measurements performed at one altitude.
