摘要: |
目标识别是SAR图像解译的重要一环,受到广泛的关注,而实时性又是评估目标识别系统性能的主要指标之一。从实时的角度出发,提出了一种快速的SAR目标识别方法。该方法采用基于Hebb学习规则的主分量分析(PCA)进行特征提取,使用多层感知器神经网络(MLP NN)进行目标分类。实验结果表明,在维持较好识别性能的前提下,该方法具有内存需求少、运行速度快的特点,能用于实时处理。 |

Abstract: |
The extensively focused target recognition is one of the important problems for SAR imagery interpretation. With the aim to real-time processing, a fast SAR target recognition system is built, which utilizes the principal component analysis (PCA) for feature extraction and a multi-layer neural network (MLP NN) as the classifier. The experimental results show that it consumes little memory and runs very fast, thus can be used in the real-time situation. |
Keywords: target recognition feature extraction PCA SAR neural network |
