摘　　要：高分辨距离象是高频区雷达目标识别的最基本的依据。文中对高分辨距离象用于目标识别的两个方面的特征进行了分析 ,提出了相关角度的概念。该概念反映了距离象与目标整体之间的相似性 ,是基于距离象目标识别的又一个重要特征 ;分析了距离象相位信息的重要性 ,指出了利用距离象相位信息进行目标识别的方法和途径。In high frequency region,the radar range profiles are chosen as feature vectors for target recognition.The profile is seriously affected by the bearing.In order to make the radar target recognition more sffective,the definitions of correlation length and correlation angle are given.In frequency domain,the most important feature of the shape of a profile is mainly contained in its spectral phase, but not in its spectral magnitude.So the spectral phase is important feature information for RTR(Radar Target Recognition) in high frequency region,and should be utilized effectively.
