基于5G SSB信号外辐射源雷达虚拟基线测向技术
Virtual Baseline Direction Finding Technology Based on 5G SSB Signal External Radiation Source Radar
摘要
Abstract
In view of the phase ambiguity problem that occurs between the phases of 5G SSB(Synchronization Signal Block)during the target detection process of 5G external radiation source radar,this study proposes a virtual baseline direction finding technology for external radiation source radar based on 5G SSB signals.The correlation of the signal structure in the 5G communication signal SSB is utilized to confirm the SSB index,and the phase angle in-formation is extracted at the corresponding SSB index positions.A phase unwrapping algorithm is adopted to reduce the phase ambiguity,and the target angle is obtained through the virtual baseline direction finding algorithm.A 5G toolkit is used to generate simulated signals for simulation analysis.The results show that the proposed method has a better direction finding effect compared with the traditional direction finding method.When the SNR(Signal-to-Noise Ratio)is-15 dB,the ambiguity resolution probability of the proposed method is 88.48%,and the RMSE(Root Mean Square Error)is 1.15°.The experimental results indicate that the proposed method can measure the tar-get angle more accurately and has a better measurement accuracy than the traditional direction finding method.关键词
