SYSTEM AND METHOD FOR DETECTION OF RF SIGNAL SPOOFING

摘要

PROBLEM TO BE SOLVED: To provide an improved system and method for detection of RF signal spoofing.SOLUTION: One embodiment of the invention includes a radio frequency (RF) receiver system. The system includes an antenna configured to receive an RF input signal and an RF signal front-end system configured to process the RF input signal to generate an equivalent digital signal. The system also includes a spoof detection system configured to analyze a power spectral density (PSD) of the equivalent digital signal and to compare the PSD of the equivalent digital signal with a predetermined baseline PSD to detect the presence of a spoofing signal component in the RF input signal.SELECTED DRAWING: Figure 1
