Abstract: Owing to the differences among scatterer distributions observed by wideband radars with different viewing angles, it is necessary to research the network radars imaging algorithm for asymmetrical spinning targets. By making use of the range profile series of spinning target obtained by two wideband radars at different locations, the scatterer association is accomplished based on the micro-motion feature invariability of asymmetrical spinning target. Then, the three-dimensional image, which can provide the real size of the target, is obtained. The simulation demonstrates the high precision of the proposed algorithm, and insensitivity to sheltering effects and RCS fluctuation of scatterers.
