Abstract

MMW (millimetre wave) imaging is considered as an effective approach to CWD (concealed weapon detection). In this paper, an experimental millimetre wave imaging system based on an aperture synthesis approach is designed. The system is used to scan a metallic object and the resulting field distribution has been recorded. To reconstruct the image, a holographic processing algorithm is applied and a focused image is obtained. The system is active and works at a single frequency, 92.5 GHz. It can be used to investigate the optimized system parameters such as antenna beam width, operating range from the target and aperture array element spacing, etc.
