Abstract :
We present design and realization of a broadband FMCW radar working in the millimeter-wave (MMW) region. The usable frequency range lies between 91 GHz and 102 GHz. The quadrature receiver signal is synthesized from a single homodyne receiver channel using Hilbert transform methods. This ultrawide bandwidth of 11 GHz is necessary for the purpose of a high resolution imaging task. Due to the fact that MMWs propagate easily through common clothing it is feasible to image objects like concealed weapons worn beneath the cloth. Imaging of humans in the MMW region is one possibility to enhance the capabilities of nowadays security checkpoints, e.g. at airports
