Terahertz imaging technology is one of the hotspots of the current research in the field of terahertz, terahertz waves have high resolution, penetration, security, counter-terrorism and security aspects for the enormous advantages. This paper describes 220 GHz radar imaging technology based on the wavenumber domain algorithm, using mechanical scanning mode and simulated target scattered points model. After the processing of algorithm, the results show the wavenumber domain algorithm can accurately reconstruct the target location and have high imaging precision. Laying the foundation for further applied, thus paving the way for the application of security imaging.
