A detection and identification method based on signal power for different types of Electronic Jamming attacks on GPS signals

In this work, a detection method is proposed for Global Positioning System (GPS) jamming attacks. GPS signals despite being an indispensable part of our life, come with a great weakness which is having a weak signal. This makes it vulnerable to external attacks like jamming and spoofing. The purpose of this study is to properly be able to identify the type of jammer affecting the GPS signal so that proper defensive measures can be applied to ensure the safety of the signal. This work is the second phase of a study based on the effect of Electronic Jammers (EJ) on GPS signals. Four different EJ are studied and the purpose is to be able to identify which one of them is affecting the signal in order to apply the appropriate defensive measure. In order to achieve this, the power of the signal is analyzed in order to achieve a threshold/interval to be able to identify the type of jammer. All of the simulations and measurements are carried on MatLAB.
