  • Patent number: 10731959
    Abstract: A deployable active radar countermeasure or “smart chaff” device includes a flexible battery or length of reflective material for passive reflection of a surveillance radar signal. Metallized antenna elements printed onto the material receive the surveillance radar signals, and RF integrated circuitry bonded to the material generates active RF echo signals based on the frequency of the surveillance signal and the length of the material. Wirebond receiving paths include reconfigurable gain amplifiers and filters for adjusting the phase and amplitude of the echo signal, and transmit paths return the echo signal to the radar source via the antenna elements. Echo signals may combine with those of other such devices, having various lengths and associated frequencies, to simulate a false return associated with a particular aircraft or moving target (e.g., simulation of Doppler shift via offset echo frequencies).

  • Publication number: 20200155084
    Abstract: For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. Additional examples are directed to applying selective filtering at a proximal end of the elongated member to provide a more stable base for distal measurements and thereby reducing the influence of measurement errors.
