Errors of Estimating the Parameters of Local Magnetic Anomalies Based on Magnetic Survey Performed at Different Altitudes by an Unmanned Aerial Vehicle

Resumo

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 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.
