摘　　要：对直升机和固定翼飞机这两类空中目标多普勒频谱测量能力进行分析,并在测量能力得到满足的前提下,针对目标的多普勒频谱提出了用形状统计量(偏度量和峰度量)作为目标识别的特征。通过对18种直升机和固定翼飞机仿真数据进行检验,证明这种方法是有效的,并且适用于悬停直升机的探测与识别。The Doppler spectrum measurement capability on air targets including helicopter and fixed-wing aircraft is analyzed firstly. The shape statistics （skewness and kurtosis） can be used as the feature for target identification with respect to Doppler spectrum of these two targets when the measurement capability is satisfied. This method is proved to be efficient by testing the simulation data of the eighteen kinds of helicopters and fixed-wing aircraft. It can also be applied to detection and identification of hovering helicopters.
