Abstract: Geophysical methods are used as locating tools and reconnaissance methods. Gravity method is used to locate underground structures and cavities using density contrast. In this paper, methods of airborne gravimetry and airborne gravity gradiometry, corrections and modern instruments of these methods have been presented. In order to evaluate the accuracy and efficiency of these methods, given a developed program, artificial data of an underground structure have been provided by forward modeling. Artificial data have been provided for earth surface and different altitude heights & then noise were added to data. Finally the results of the simulation and the accuracy of the presented instruments for different altitude heights have been compared. In conclusion effective solutions to mitigate the probable detection of buried structures and the improvement of camouflage processes aginst airborne reconnaissance are provided.
