摘要

Micro-motions of targets will introduce additional frequency modulation to radar returns, which is called micro-Doppler effect. The micro-Doppler signature will be changed in ISAR imaging after dechirping and motion compensation. Two modified models for micro-Vibration and micro-Rotation in ISAR imaging is introduced and verified by simulation. Finally, method of micro-motion parameter estimation is addressed.
