Abstract

Inverse Synthetic aperture radar (ISAR) is widely used to observe the space moving target, on which the motion of spin, vibration and rotation will introduce the micro-Doppler (m-D) effect, and results in the smear imaging. When the space target has a micro-Doppler effect, it will produce frequency modulation for the radar echo and cause serious interference. In this paper, the micro-spin model is constructed, and the echo of micro-spin scattering is processed respectively by the time-frequency analysis. A new method of eliminating the micro-Doppler effect is proposed to improve the ISAR imaging. By the experiments and performance analysis, the validity of the proposed algorithm is demonstrated.
