基于PCS与Ratio融合的GNSS欺骗检测方法研究
Research on GNSS spoof detection method based on PCS combined with Ratio
摘要
Abstract
A spoofing detection algorithm based on power combind with signal quality montoring(PCS)combind with Ratio(PCSR)is proposed to improve the performance of spoofing detection,in response to the problem of high fluctuation in the detection performance of PCS during the traction stage.The fusion process of the PCSR algorithm uses a weighting factor to linearly weight the amplitudes of the processed PCS and Ratio,and adjusts the contribution of PCS and Ratio to PCSR by changing the weighting factor.The experiment used data scenario 4(DS4)of texas spoofing test battery(TEXBAT)from the University of Texas at Austin as the dataset to compare and analyze the deception detection performance of PCS,Ratio,and PCSR algorithms.The experimental results show that PCSR has higher detection probability and accuracy,better immediacy and robustness,and a wider detection range.The proposed PCSR algorithm combines the advantages of both PCS and Ratio algorithms and has better spoofing detection performance.关键词
