Detection of Spoofing of Satellite Navigation Receivers Based on Statistical Model of DAC
Abstract: Since real signals and spoofing signals are overlapped in time domain, frequency domain and time-frequency domain, it is not easy to distinguish them. In this paper, a new identification method based on the model of digital-to-analog converter (DAC) is proposed on a condition that the devices of transmitter and jammer are in desired state except the DAC. Firstly, the DAC is modeled with the integral non-linear (INL) and differential non-linear (DNL) to extract the parameter vector; secondly, the spoofing signals are identified by using a LRT detector and a naïve method; lastly, the effectiveness of the proposed method is verified via simulation.
