摘要

摘要: 提出了一种改进的稀疏保持投影(Sparsity Preserving Projections, SPP)特征提取方法。该方法将SPP特征提取与局部保持投影(Locality Preserving Projection, LPP)特征提取思想相结合,构造新的目标函数求解投影向量,保证了投影空间内样本的稀疏重构误差达到最小的同时使同类样本间距最小。利用美国运动和静止目标获取与识别(Moving and Stationary Target Acquisition and Recognition, MSTAR)实测SAR数据进行实验,实验结果表明在不利用目标成像方位信息情况下平均识别率最高可达97.81%,明显地提高了目标的识别结果,是一种有效的SAR目标识别方法。

Abstract: We have proposed an improved Sparsity Preserving Projection (SPP) method to implement target feature extraction. It combines the SPP feature extraction using the idea of the Locality Preserving Projection (LPP) scheme to build a new objective function, which can not only maintain the relationship of sparse reconstruction between the samples but also minimize the distance between similar sample types in the projection space. Experimental results with Moving and Stationary Target Acquisition and Recognition (MSTAR) Synthetic Aperture Radar (SAR) data sets show that the average recognition rate using the proposed method is up to 97.81% without knowing the target to be azimuth, which can improve the target recognition result even further for obvious reasons. The proposed method is an effective one for SAR target recognition.
