Frequency propagation in the radar band in order to detect and specify the targets and Metals  and objects and Gold and Silver  first has the field pressure on the surface of the desired target  and then the transmitted frequency is applied to the internal field of the target and by applying the field pressure action On the surface of the target the condition of entering the frequency on the field of the target is carried out and then the frequency field of the metal detector of the frequency image scanner on the desired target field takes the absorption and combination mode  and then the conversion operation is performed and the combined and converted field is placed in the reflection mode  The reflection of the desired target field  which is set in the VDI Number settings in the Edit and Threshold separates the Surface and Size and then performs the Separation and Discrimination process and the Metal Detector uses a frequency image scanner or GPR or a manual ground radar scanner or Ground Handy Radar Scanner or The ground penetrating radar Scanner which is designed according to the principles of low frequency radar uses this diffusion law to absorb and combine and convert and detect the reflection of the target field according to the settings for the Separation and Discrimination of Metals and Gold and Silver in Depth.
