The micro-Doppler effect based on the inverse synthetic imaging ladar is studied
and the influence of the high carrier frequency and the bandwidth of laser signal on the range profiles is also analyzed.Furthermore
the corresponding parameters equation of micro-Doppler is constructed and then the influence of the fast-time on the micro-Doppler effect is also discussed.Based on the Extended Hough Transform and the erosion and dilation operations in binary mathematical morphology
a novel extraction method of micro-Doppler effect is proposed for the inverse synthetic imaging ladar accordingly.The simulations are given to verify the theoretical derivation and the validity of the proposed method.In addition
the validity of the measurement of the inverse synthetic imaging ladar for the micro-motion at the centimeter-level or the millimeter-level is also illustrated in the simulations.
