a TDI CCD pendular aerial camera has a larger angle of view
but it has the problem of image motion in the direction of pendulum swing. A real angle IMC (image motion compensation) is therefore proposed to solve this problem. Experiments proved the correctness of real angle IMC. The error of FMC (forward image motion compensation) is analyzed taking a CT-F3 camera as an example
and the system performance suggested are as follows: the precision of TDI CCD integral time should be more than 5‰
and the compensation precision of scanning mirror should be over 1%.
