【摘要】 随着高分辨率雷达的发展,一维距离像识别已成为雷达目标识别的重要方法之一。为了消除一维距离像的平移,将一维距离像变换到频域,提取其频谱信息作为识别特征,并依据Fisher判据,将高维特征空间数据降到一维空间,提高了算法的实时性。仿真结果表明这是一种方便有效的识别方法。更多还原

【Abstract】 With the development of high resolution radars,one-dimensional range profile identification has been becoming an important method in radar target identification.In order to eliminate errors caused by shift,range profile is transformed to frequency domain,and its spectrums is picked as attribution vector.Then,according to Fisher algorithm,high-dimensional attribution vector is transferred to one dimension domain;consequently,real-time property is improved.Simulation results show that it is a simple and efficient identification method.更多还原
