The inverse synthetic aperture imaging lidar（ISAIL）is a new kind of radar where the inverse aperture technique is introduced into the imaging lidar.ISAIL can obtain the image of target with ultra-high resolution,which provides a new approach for extraction of target′s fine micro-motion features.In the paper,the micro-Doppler（m-D）features of vibration in ISAIL are analyzed,and the influences of high carrier frequency and large bandwidth of laser signal on m-D features are discussed.The m-D features in ISAIL are compared with that in microwave inverse synthetic aperture radar（ISAR）,and the simulations demonstrate that the ISAIL can provide adequate resolution for extraction the m-D features of target with tiny micro-motions.
