Abstract

Abstract

Wide band can be achieved in terahertz (THz) spectrum, so a high resolution terahertz imaging system can be realized according to the radar imaging theory. The stepped THz pulse is obtained by mixing and multiplying the microwave source, and a 220 GHz terahertz active imaging system is designed and developed. The resolution experiments of two reflectors imaging are performed in an anechoic chamber, and the range experiment is done outdoor, which shows that the resolution is up to 4 cm and the range reaches 10 m.
