| 摘 要： | 根据联合变换相关理论和光的衍射理论,定量分析了联合变换相关中两相关输入物长宽比与输出相关点形状间的关系.结果表明:输入相关物长宽比影响相关点的形状,当相关物长宽比过大时,将使相关点形状严重偏离圆斑形状,从而影响相关点的探测和精确定位.

| Abstract: | The relation between output correlation spot shape and length width ratio of input correlation image was analyzed quantificationally by using of diffraction theory in the joint transform correlation. Through theoretical analysis and test research,conclusions show that with the input correlation image's length width ratio becoming smaller,the output correlation spot shape approaches circular spot and with the input correlation image' s length width ratio becoming bigger,the output correlation spot shape departures circular spot. |

| Keywords: | Joint transform correlation Length width ratio of input image Correlation spot shape |
