雷达目标特征信号与运动模式的相关性研究
摘要
Aerial and ground targets motion modes have a close relationship with their pose angles, hence with radar signatures. An analysis on target pose angular rates under different motion modes is performed firstly. Expressions of radar signatures are then derived, including radar cross section (RCS), angular glint errors, and high resolution Doppler profile. By taking a two-scatterer simple target as an example, we explore the relationship between the above signatures and target pose angular rates. The relationship between radar signatures and motion modes are then developed. Finally, the simulation results of radar signatures for multiple-scatterer complex target validate the theoretical analysis, and show that it is feasible to identify different motion modes based on radar signatures. The conclusions are significant for the research of motion mode identification, maneuver detection, and maneuvering target tracking and interception using radar signatures.
