Abstract: This paper discusses the problem of low elevation target height estimation for multiple-input multiple-output (MIMO) radar in multipath environments. Beamspace compresses the data and is ideal for reducing the computational burden of elevation estimation. To accurately obtain the height parameter of the target, we propose a height estimation method based on a beamspace joint alternating iterative algorithm in MIMO radar. This method mainly converts the reduced-dimensional MIMO radar element space data into beamspace and whitens it to improve the reliability of the data. It then uses a simplified model to obtain the initial value of the elevation and combines the target reflection coefficient and the target elevation for alternate esti-mation. Finally, we calculate the target height using the obtained elevation information. Simulation verifies that the proposed algorithm has good estimation accuracy and robustness.
