一种基于调制谱的空中目标识别方法

摘要

雷达目标的微多普勒特征在雷达目标探测与识别中受到越来越多的关注,正在成为目标探测与识别领域的新兴研究方向.介绍了一种基于调制谱的空中目标识别方法,根据空中目标回波、综合时域的幅度信息、时域的相位信息和频域的微多普勒信息,将空中目标分为直升机类目标、螺旋桨类飞机目标和涡扇类飞机目标,利用实测数据对结论进行验证,表明该方法可以用来对这些目标进行分类.%The Characteristics of the micro-Doppler radar target are more and more paid attention, and it is becoming an emerging area of research on target detection and recognition. This paper introduces a modulation spectrum's method for aerial target recognition. We can divide the air targets into helicopter, propeller and turbofan type aircraft base on amplitude information of the time domain, phase information of the time domain and frequency domain of the micro-Doppler information. It shows that the method can be used to classify these objectives using the measured data.
