Terahertz imaging technology is one of the hot spots in the field of terahertz research. Terahertz waves have the advantages of high resolution, good penetration and safety, and have great advantages in counter-terrorism and security inspection. This paper introduces 220GHz radar imaging technology based on wavenumber domain algorithm. The target scattering point model is established by using the mode of mechanical scanning and simulation. The results of the algorithm show that the wavenumber domain algorithm can accurately reconstruct the target location with high imaging accuracy, In order to further lay the foundation for the measured data, which paved the way for the application of security imaging.
