Application of radar signal processing in terahertz imaging

The paper points out terahertz imaging algorithm has yet to be developed, in contrast to other matured imaging algorithm. It may be said that there is a terahertz gap in the field of imaging algorithm. Then, based on the classification of terahertz imaging, the relationship between radar imaging and terahertz imaging is discussed. The terahertz radar target signature is studied, and the ultimate imaging resolution of different terahertz sources is analysed. Finally, a review of terahertz radar signal processing and imaging algorithm is presented.
