摘要
Abstract
Terahertz radiation imaging enables passive target detection.To accurately obtain terahertz radiation images of targets and the background environment,a terahertz radiation imaging system is designed.The system performs spatial sampling of the field-of-view through two-dimensional scanning,employs a 0.5 m reflector antenna to collect radiation signals into a radiometer with a center frequency of 0.15 THz,and then reconstructs the radiation image of the field-of-view by combining the voltage signal output from the radiometer with spatial sampling parameters.To investigate ground target detectability,visible light,0.15 THz,and infrared images of the field-of view are measured under day/night and rainy/foggy conditions.Experimental results demonstrate that the 0.15 THz radiation imaging system can capture radiation energy from the cosmic microwave background,enabling accurate detection of high-reflectivity targets during both day and night,as well as in rainy conditions.关键词
