无人机尾翼对雷达导引头目标检测影响分析

The Influence Analysis of the Unmanned Aerial Vehicles(UAVs)Tail Rotor Blade Echoes for Radar Seeker Target Detection

无人机已经成为现代战争的重要空中威胁之一,同时可作为理想靶标广泛应用于各类试验中。无人机尾部涡轮旋桨回波会影响雷达导引头对机身信号的检测和跟踪。简要介绍了无人机尾部旋翼的雷达时域回波模型,在某波段下对尾部旋翼回波进行了仿真,给出了信号的频域特征,分析了无人机涡轮尾翼对雷达导引头目标检测信噪比的影响,并给出了结论。

The Unmanned Aerial Vehicles （UAVs） have become one of the important aerial targets threat sources in the modern warfare, and at the same time, they have been extensively adopted as ideal targets in varied kinds of experimental tests. The echoes of the UAV tail rotor blade will affect the signal detecting and tracking results of the radar seeker. This paper briefly described the time domain radar echo model of the UAV tail rotor, the simulation experiments are carried out to character the property of the tail rotor＇s echo signal under a specific given frequency, the frequency domain characteristics were presented, the effect of the target detection SNR caused by the tail rotor blade was analyzed, and the conclusion was given.
