| Abstract: | Based on the working theory of the CCD vertical target measurement system,target capture ability of the CCD vertical target measurement system,as for the aspects including the sensitivity,the exposure,and the resolution of CCD,the degrees of illumination,and the contrast gradient between background and targets,were researched.The concerning calculation methods were given.Especially as for hour of a whole day captures for those target which were dark,small,and quick moving,the method of selecting wave band l... |
