DIGITAL BEAM-FORMING FOR SIMULTANEOUSLY MITIGATING WEAK AND STRONG INTERFERENCE IN A NAVIGATION SYSTEM |
摘要 |
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. |
