摘要
在飞机目标识别中 ,提取螺旋桨的调制特性十分重要。有关这方面的研究虽不少 ,但在实际中 ,还存在另外很多作周期性运动的构件 ,它们同样包含丰富的目标信息。因此 ,将螺旋桨调制特性的研究进行推广 ,就一般性的周期运动构件的雷达调制回波特性提取方法进行论述 ,并提出识别调制源数目的方法 。
In radar target recognition of airplane, the modulation characteristics of propeller is crucial, and there are some papers on this respect as well. But in reality, there are many other components making periodic movement, and they also contain rich information of the object. So here we'll analyze the modulation phenomenon in general, and present the modulation feature extraction methods to identify the number of modulation sources in detail. Finally, we use the measured and simulated data to verify the method.
