  • System and method for generating high power pulses
    Patent number: 9900203
    Abstract: A system and method for generating high power pulses including a photoconductive semiconductor switch (PCSS), a laser for triggering the PCSS and a bipolar pulse generator coupled to the PCSS. The bipolar pulse generator is activated when the PCSS is triggered. A bipolar pulse is generated by the activated bipolar pulse generator. A modulator unit modulates the bipolar pulse to create a modulated bipolar pulse. The modulator unit is a nonlinear transmission line (NLTL).

  • Video rate passive millimeter wave imaging system
    Patent number: 7170442
    Abstract: A passive millimeter wave imaging system that includes at least one millimeter wave frequency scanning antenna and multiple beam formers collecting narrow beams of millimeter wave radiation from a two-dimensional field of view. The collected radiation is amplified and separated into bins corresponding to various vertical and horizontal beam orientations. In a preferred embodiment the beam formers include one phase processor and 192 frequency processors. Two dimensional images of a target are obtained by the simultaneous detection of signal power within each beam and converting it into pixel intensity level at a rate of 30 frames per second.
