In order to avoid bad bistatic geometry cases and offer better concealment and anti-interference ability, a novel kind of bistatic inverse synthetic aperture radar (ISAR) configuration, named shorebase-shipborne bistatic ISAR, is presented. In this paper, the Doppler frequency model of the received signal for shorebase-shipborne bistatic ISAR is proposed, when both the target and the receiver ship have nonstationary three-dimensional (3-D) rotational motion. An analysis of the Doppler shift and image aliasing induced by the receiver ship's rotational motion is given. To eliminate the effects of receiver ship's rotational motion, a new image reconstruction method in combination with range-instantaneous Doppler (RID) technique and rotational motion compensation is proposed. The simulated results demonstrate the effects of the receiver ship's rotational motion and the effectiveness of new image reconstruction method.
