    Conference Proceeding

    In this paper, a UWB imaging camera with 7x7 active pixels is reported. The UWB camera consists of a CMOS chip that interfaces with 2x2 3D omni-directional UWB antennas. This receiving camera forms 7x7 simultaneous beams in two dimensions and includes an array of on-chip pulse-energy detectors for each active pixel. With 3cm of spacing between antenna elements, this 2D UWB camera achieves a 10deg spatial resolution and plusmn30deg of spatial coverage in each dimension.
