摘要

In view of the many scenes of unmanned aerial vehicle(UAV)detection,a third-party signal source is used to design a receiver to monitor the UAV.It is of great significance to understand the reflection of the signal illuminating the UAV.Tak-ing the communication base station(BS)signal as the third-party signal source,and considering the complete transmission link,reflection changes and loss fading of the communication signal,this study conducts model fitting for irregular UAV targets,sim-plifying complex targets into a combination of simple targets.Furthermore,the influence of the dielectric constant of the tar-get surface and the signal irradiation angle on the signal reflec-tion is analyzed.The analysis shows that the simulation results of this model fitting method are consistent with the results of other literature,which provides theoretical support for the detec-tion of low and slow small targets such as UAVs.
