Three-dimensional reconstruction of precession warhead based on multi-view micro-Doppler analysis

The warhead of a ballistic missile may precess due to lateral moments during release.The resulting micro-Doppler effect is determined by parameters such as the target's motion state and size.A three-dimensional reconstruction method for the precession warhead via the micro-Doppler analysis and inverse Radon transform(IRT)is proposed in this paper.The pre-cession parameters are extracted by the micro-Doppler analysis from three radars,and the IRT is used to estimate the size of targe.The scatterers of the target can be reconstructed based on the above parameters.Simulation experimental results illus-trate the effectiveness of the proposed method in this paper.
