Abstract:
To locate the near-field moving targets, an efficient algorithm for Doppler frequency, range and bearing estimation of near-field moving targets is presented. The frequency of target echo is estimated using 1-D multiple signal classification (MUSIC) algorithm at first. Then according to the different frequencies of targets, target echo is separated through temporal filtering. The range and bearing of each target is estimated through employing 2-D MUSIC algorithm finally. The 3-dimensional parameter of near-field moving targets can be estimated accurately using the algorithm provided in this paper. Simulation results are presented to prove the validity of the algorithm.
