The math model about synchronism controlling between line scanning rate of CCD and object moving speed in the TDI CCD intersection measuring system is established.

建立了TDI CCD交汇测量系统中CCD行扫描速率和目标运动速率同步控制的数学模型。

This model synthetically considers length and velocity of target object, line scanning rate of TDI CCD, magnifying power of imaging system, size of pixel, and so on.

该模型综合考虑了目标长度、目标运动速率、TDI CCD行扫描速率、成像系统放大倍数、TDI CCD像元尺寸等因素。
