| Abstract: | Aiming at the widely existing global navigation satellite system (GNSS) interference, the positioning method based on received signal strength (RSS) is adopted, which has problems such as great difficulty in extracting RSS value, large positioning error in complex scenes such as closed and multipath in urban environment. A centroid localization method of GNSS jamming source based on signal propagation correction is proposed. In this method, the carrier to noise ratio information output by GNSS receiver is used, and the influence factors of interference signal propagation are predicted by the neural network method, and the location of GNSS interference source is realized by centroid weighting. Experimental results show that the positioning accuracy of this method is significantly improved. |
