Abstract
A method for locating an object buried in soil in which at least one electromagnetic signal is imparted onto the buried object, thereby generating an electromagnetic field around the buried object. The electromagnetic field as well as at least one electromagnetic property of the soil surrounding the buried object, such as moisture content, temperature and density, is then determined. Data related to the at least one electromagnetic property is transmitted to a data processor in which at least one algorithm is applied to the data, whereby a location of the buried object is determined.
