摘　　要：为解决PD引信对悬停直升机的探测问题,文中根据典型防空导弹PD引信和直升机旋翼运动特点,推导并建立了PD引信的悬停直升机旋翼回波数学模型,结合短时傅里叶时频域分析技术对仿真结果进行分析,得到了悬停直升机旋翼的时频特性。对比外场试验数据,仿真数据与试验数据相一致,理论模型得到验证,为后期的引信对直升机的启动特性研究奠定基础。In order to solve the problem of PD Fuze detecting hovering helicopter,according to the characteristics of typical air defense missile PD Fuze and helicopter rotor motion,this paper deduces and establishes the hovering helicopter rotor echo mathematical model of PD Fuze,and analyzes the simulation results by combining the short-time Fourier time-frequency analysis technology,and obtains the time-frequency characteristics of hovering helicopter rotor.the theoretical model is verified by anatomizing data from digital simulation and outdoor experiment.the result lay the foundation for Fuze detecting algorithm against helicopters.
