| 摘 要： | 首先分析直升机目标回波组成，提取了旋翼回波微多普勒，通过仿真，分析比较了不同叶片数目和不同入射角时旋翼回波微多普勒，表明旋翼微多普勒分布特征与入射角无关，为提取稳定的直升机雷达特征提供了思路。

| Abstract: | Echo components from a helicopter target are analyzed. Micro-Doppler is extracted from the echo of helicopter. By simulation micro-Doppler is analyzed and compared when the number of the blades and the angles of incidence are different, which indicated the micro - Doppler distribution feature is independent of the angle of incidence. The conclusion points out a way for extracting stable radar feature of a helicopter target. |
