Abstract:

Aiming at improving the robustness in pre-processing and extracting features sufficiently for Synthetic Aperture Radar (SAR) images, an automatic target recognition algorithm for SAR images based on Deep Belief Network (DBN) was proposed. Firstly, a non-local means image despeckling algorithm was proposed based on Dual-Tree Complex Wavelet Transformation (DT-CWT); then combined with the estimation of the object azimuth, a robust process on original data was achieved; finally a multi-layer DBN was applied to extract the deeply abstract visual information as features to complete target recognition. The experiments were conducted on three Moving and Stationary Target Acquisition and Recognition (MSTAR) databases. The results show that the algorithm performs efficiently with high accuracy and robustness.

摘要:

针对合成孔径雷达图像预处理鲁棒性不足、特征提取及利用不充分等问题,提出了一种基于深度置信网络的合成孔径雷达(SAR)图像目标自动识别算法。首先提出一种基于双树复小波变换(DT-CWT)的非局部均值图像降斑算法,并结合目标方位角估计实现对原始数据鲁棒的预处理;最后,引入多层深度置信网络提取针对合成孔径雷达目标的深度抽象视觉信息作为特征并完成识别任务。采用3类运动与静止目标的获取与识别(MSTAR)实测数据进行的仿真实验结果表明,所提算法具有较高鲁棒性和识别率。
