Research on Imaging Algorithm of Millimeter Wave Radar Based on Stolt Interpolation

Abstract

The paper presents an imaging algorithm of millimeter wave radar. The radar scans the space by changing the antenna positions and acquires the signals at different frequencies in each point. The stolt interpolation algorithm converses $k_{x}^{\prime}-f$ domain to $k_{x}^{\prime}-k_{z}^{\prime}$ domain. Then by inverse Fourier transform we obtain the image of the object in the space plane. Finally, the effectiveness of the algorithm is verified by MATLAB simulation.
