摘要：

A super-resolution three-dimensional (3D) imaging method using spectrum estimation theory and narrowband multiple-input-multiple-output (MIMO) radar is presented. First, the 3D echo signal model is built in a narrowband bistatic MIMO radar with uniform linear transmit array and uniform rectangular receive array. Then, the high accuracy position estimation of target's scattering centres is obtained via spectrum estimation theory only with single snapshot, and the scatter intensity estimation is obtained by least-square estimation. The 3D image of the target is thus reconstructed. The proposed method is especially suitable for high-speed manoeuvring targets with complex motion. Finally, comparative simulation results are presented and the performances under noise and error case are analysed to demonstrate the effectiveness of the method.
