%X Synthetic aperture ladar(SAL), whose carrier is laser, makes use of synthetic aperture processing to improve the resolution of images. Vibrations from the platform of SAL would have effects on the imaging quality of SAL, because of the short wavelength of laser. Firstly, based on the paired-echoes theory, the effects of angle vibration on the imaging quality are analyzed. Then, the amplitude and the position of the paired-echoes are deduced in detail. The conclusion is the effects of the vibrations would be the paired false target which the traditional windowing method to suppress the side-lobes has no effect on. Finally, the simulations prove the validity of the analysis. It provides theoretical foundation for SAL system analysis and design.
