Recognition of Wobbling and Nutating Cone-shaped targets
Recognition of wobbling and nutating cone-shaped targets is a major challenge in space target recognition area. In this paper, we develop a signal model of multiple scattering centers on the wobbling and nutating cone-shaped targets, analyze the microDoppler characteristics of their echo. It is concluded that the micro-Doppler features have remarkable differences due to their different micromotion. Therefore, we apply viterbi algorithm to extract the micro-Doppler and micro-motion parameters, the simulation results demonstrate that the wobbling and nutating cone-shaped targets can be recognized effectively in this way.
