摘要 针对高分辨距离像(HRRP)的姿态敏感性和平移变化敏感性,提出用HRRP偶数阶中心矩特征进行目标识别.该方法用小波去噪方法提高HRRP的信噪比,在此基础上提取具有平移不变性的中心矩作为特征向量,为了降低特征矢量的维数,可以只把具有较强稳定性的偶数阶中心矩作为特征向量,以适用于组合特征的最近邻模糊分类算法对中心矩特征进行处理.实测卫星数据的验证结果显示,该方法在减少存储量和计算量的同时取得了非常好的识别效果. Even rank central moments of high resolution range profile(HRRP) are used for target recognition in the new proposed method.Wavelet denoising is used to enhance the signal noise rate(SNR) of HRRP.Then central moments are extracted from the denoised HRRP.Even rank central moments can be used as features for target recognition because they are very stable.Nearest neighbor fuzzy classifier(NNFC) is used to process the central moments features vector.The experimental results based on real satellites data show t...
