摘要：This paper establishes imaging model for rigid body micro-motion target with rotating parts, and derives the formulas of micro-Doppler induced by target with rotation. To obtain well-focused inverse synthetic aperture radar image of rigid body micro-motion target with rotating parts, low frequency filter algorithm is presented to separate the echoes of the rigid body from that of the micro-motion parts. The results of measured data confirm the effectiveness of the proposed method. Defence Science Journal, 2013, 63(5), pp.521 -523 , DOI:http://dx.doi.org/10.14429/dsj.63.4087
