摘要：
A compensation method of target radial motion is formulated and applied to obtain focused images in inverse synthetic aperture radar (ISAR). The basic scheme is to estimate the radial motion of the target centroid and to compensate in such a way that range and Doppler of the centroid are kept constant. Resultant images of X-band ISAR for ship and aircraft indicate that the estimation accuracy of velocity, acceleration, and jerk are considered to be satisfactory.
