旋翼微多普勒对直升机的分类和识别具有重要意义。过去，转子的叶片被建模为一根杆。然而，叶片有不同的尖端形状，这可以作为直升机识别的补充信息。推导了三种不同叶尖类型的叶片信号模型。通过对时频域理论和实验数据的分析，揭示了翼尖形状在直升机识别中的潜力。
Micro-Doppler of a rotor is of great importance in classifying and identifying a helicopter. In the past, the blade of a rotor was modelled as a rod. However, the blade has different tip shapes, which can be supplementary information for helicopter identification. The signal model of blades with three different tip types is derived. By analysing the theoretical and experimental data in the time–frequency domain, the potential of the tip shape in helicopter identification is shown.
