Analysis of radar angle measurement error caused by active fluctuation of multiple scattering points

This paper analysis the radar angle measurement error caused by active fluctuation of different scattering points. By using artificial electromagnetic surface metamaterials such as Frequency Selective Surface (AFSS), we can easily achieve our goals to modulate the RCS of the target. The real target is own to multiple factors such as target distance, flight attitude, and so on, which will cause the difference of measurement data. The analysis of materials is becoming more and more popular, and scholars usually focus on how to increase or decrease the RCS of materials. However, there is little study on establishing linkages between materials and angle measurement. This paper mainly study the linkages between the modulate of materials and the radar angle measurement. and the optimal protection model is given by different control methods of scattering points. Finally, the simulation results show that the model can increase the radar angle measurement error and improve the target protection ability within the allowable range of materials.
