Radar, such as frequency-modulated continuous wave (FMCW), can be used to analyze characteristics of an item. The radar can be emitted by a mobile device, such as a smartphone, that has radar technology incorporated as part of it. The radar backscatter of various portions of an item can be analyzed to determine whether the item is likely counterfeit or authentic.
