“…These are (1) time-domain filtering [32,33], (2) frequency-domain filtering [34,35], (3) spatial filtering [24,36], and (4) time-frequency filtering [22,37]. The first two types of filtering are conventional.…”

“…In addition, post-correlation method requires more time to detect interference than pre-correlation method. Therefore, the pre-correlation method using adaptive notch filter is selected to detect the interference (Capozza et al 2000, Chien et al 2010) and is applied to multiple ground stations system in this paper.…”

“…Detection and mitigation methods of the CWI by using the adaptive filter have been studied recently and can be classified into two approaches: time-domain (Cho & Lee 1993, Choi & Cho 2002, Borio et al 2008, Chien et al 2010) and frequency-domain approaches (Capozza et al 2000, Balaei & Dempster 2009). These approaches have a limitation on detection and mitigation of swept continuous wave interference, because its sweep rate degrades the signal tracking performance of the adaptive notch filter.…”

For a GNSS receiver's robustness against RFI and the high accuracy of navigation solution in GNSS, interference source detection and mitigation are needed. In this paper, an adaptive lattice IIR notch filter is employed to track single-tone continuous wave and swept continuous wave interference signals, and an interference detection method is proposed. Furthermore, this paper presents interference source characterization algorithm using multiple ground stations' interference detection results. The measurement of the signal powers from each ground station is used to build weighting factors to estimate the type of the interference. The performance of interference detection algorithm is simulated for scenarios of GPS signal in the presence of single-tone continuous wave interference and swept continuous wave interference.
