提出了一种基于散射中心估计的目标识别方法,该方法首先利用AIC和MDL标准预测目标散射中心个数,然后基于TLS—ESPRIT算法估计散射中心的幅度和位置信息并提取散射中心相对距离作为识别特征,该特征在一定角度范围内具有旋转和平移不变性,最后通过对三类飞机目标的分类识别,验证了这种方法的有效性和稳健性.
An airplane identification method based on scattering centers estimation is proposed. First of all, the number of scattering centers is reckoned by AIC and MDL , then the amplitude and position of scattering centers are estimated based on ESPRIT. The feature of relative range is extracted, which is rotational and translational invariance. Finally by identifying three kinds of airplanes, the effectiveness and robustness of the proposed method are testified.
