Abstract

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.

First claim

What is claimed is:

1. A radio frequency (RF) receiver system comprising:
an antenna configured to receive an RF input signal;
an RF signal front-end system configured to process the RF input signal to generate an equivalent digital signal; and
a spoof detection system comprising:
a memory configured to store a predetermined baseline power spectral density (PSD) corresponding to a baseline RF signal in which the spoofing signal component is known to be absent;
a PSD process…
