Radio Fingerprinting

Abstract

Radio Fingerprinting is very vast and diverse concept and it can be applied using one of the different methods. Because of Communication Security and Intelligence gathering, it has become more popular. In the Present communication scenarios, the voice / data is highly secured because of complex encryption algorithms. However we can detect the transmitters using their electronic signature known as Radio Fingerprinting. We took different type of transmitters operating in different modes and extracted phase information of the radio signals, recorded in Intermediate Frequency (IF). It was the Steady State Analysis using the available Matlab tools to discriminate different set of emitters. Using the pattern with which phase is changing, we were able to distinguish the given set of transmitters with good accuracy. However signal data library development and more can be achieved in future.
