径向分辨率 meaning in Chinese

radial resolution
radial resolving power

According to the fact that iris images cannot be compared for their different resolutions , a new method for normalizing iris region into fixed resolution by using minimum inner boundary resolution and minimum radius difference of inner boundary and outer boundary is presented
摘要针对虹膜区域图像大小不同，难以实现虹膜的比较问题，提出了根据虹膜最小内边界周长确定角度分辨率和根据虹膜最小内、外边界半径差确定径向分辨率的方法，将不同分辨的虹膜图像转换为相同分辨率的矩形区域。
The 3d imaging using monopulse angle measurement and range profile is analyzed , the imaging using one or multiple profiles are compared . the problem of target recognition using 3d monopulse imaging is discussed . to improve the recognition under low range resolution , the range profile and angle measurement are combined to get 3d information and amplitude of scatters
分析了单脉冲和距离维高分辨成像结合得到目标三维像的方法，比较了利用单幅距离像和多幅距离像的成像效果；在此基础上，分析了利用单脉冲三维像进行目标识别面临的问题；为了在较低的径向分辨率的条件下提高识别的效果，提出综合利用散射中心的角度信息和幅度信息，采用正交方法及多幅距离像匹配方法进行目标识别。
