Performance Analysis of GNSS Interference Detection Parameters

ProceedingsIn this paper, an adaptive lattice IIR notch filter is employed to track narrowband single-tone and swept continuous wave interference(CWI), and an interference detection method is proposed. The detection parameters are selected by using their unique characteristics, according to the type of received interference. The performance of the detection parameters is simulated for scenarios of GNSS signal in the presence of single-tone and swept CWI. The detection probability according to the power of the interference is perfect when jammer to signal ratio(JSR) of single-tone CWI is above than 15dB and JSR of swept CWI is above than 25dB.DAPA/ADD/NGR
