  • Patent number: 11005178
    Abstract: The subject matter described herein relates to various antenna element configurations, antenna array configurations, their operations including various systems and methods to generate modulated data for transmission by an RF antenna array via an optical processing engine. The subject matter includes optical processing engine structure and methods (e.g., modulating in the optical domain, MIMO and spatial modulation via RF beam formation, coherent transmission of RF signal components, coherent operation of spatially separate RF antenna arrays) that may be implemented with the various RF antenna array structures. In some examples, the system combines the virtues of digital, analog and optical processing to arrive at a solution for scalable, non-blocking, simultaneous transmission to multiple UE-s. Much of the system architecture is independent of the RF carrier frequency, and different frequency bands can be accessed easily and rapidly by tuning the optical source (TOPS).

  • Patent number: 10871468
    Abstract: This disclosure relates to non-contact inspection of material for identifying and estimate composition of a material under inspection. Traditionally, material inspection is an invasive process involving contact based approaches. A radar-based approach requires placement of the radar at a specific location, which is a challenge since amplitude of the reflected signal, depends on the distance from the material under inspection. The present disclosure addresses this technical problem by providing a Continuous Wave radar-based approach that is based on absolute slope at extrema points on the reflected signal from the material under inspection.

  • Patent number: 10698097
    Abstract: A multi-beam photonic monopulse comparator is disclosed. Photonic inputs incorporating M component wavelengths are split into equivalent inputs for each quadrant subarray and array element (e.g., N array elements in each quadrant subarray). Within each array element, the component wavelengths are apodized by attenuators and the apodized input signal modulated by a received inbound RF signal (via broadband Mach-Zehnder electro-optical modulators). The resulting positive-polarity and negative-polarity modulated photonic signals are demultiplexed and each component wavelength time-delayed. Time-delayed wavelength-selective optical delay channels are copied and combined by single mode/multi-mode (SM/MM) couplers into photonic antenna beams and simultaneously generated photonic comparator outputs (elevational difference, sum, azimuthal difference) for each component wavelength.

  • Patent number: 9379439
    Abstract: A phased-array antenna system includes an array of antenna feed elements that produces a radiation pattern to provide spot beams within which to receive a signal in a frequency band and carrying communication from a terminal at a known geographic location. A beamformer forms the spot beams; and a channelizer divides the frequency band into frequency subbands, and measures power levels of the signal over respective frequency subbands. And an antenna controller selects a frequency subband based on the measured power levels indicating that the signal includes an identifiable interference, and calculates a set of beam weights based on the measured power level over the selected frequency subband, and based on the known geographic location of the terminal. The beamformer, then, forms the spot beams based on the calculated set of beam weights to thereby suppress at least some of the identifiable interference from the signal.

  • Patent number: 8791854
    Abstract: One embodiment of the present invention relates to a radar transmitter comprised within a single integrated chip substrate, which is capable of continuous beam steering of a transmitted radar beam as well as an option to change the physical position of the origin of the transmit radar beam. The radar transmitter has a signal generator that generates an RF signal. The RF signal is provided to a plurality of independent transmission chains, which contain independently operated vector modulators configured to introduce an individual phase adjustment to the high frequency input signal to generate separate RF output signals. A control unit is configured to selectively activate a subset of (e.g., two or more) the independent transmission chains. By activating the subset of independent transmission chains to generate RF output signals with separate phases, a beam steering functionality is enabled. Furthermore, the subset defines a changeable position of the transmitted radar beam.

  • Patent number: 8717229
    Abstract: An active antenna array is arranged to activate subsets of switchable elements causing the antenna to form a first beam having a first beam pattern, and later to form a second beam having a second beam pattern of substantially identical far field radiation pattern to the first beam pattern but with different origins. A receiver receives radiation reflected from a target back to the antenna when the antenna is configured with the first beam pattern and then when configured with the second beam pattern, and compares the phase of the radiation received at the receiver when the antenna is configured with the first beam pattern with the phase of the radiation received at the receiver when the antenna is configured with the second beam pattern to provide a phase difference signal. A target locating means determines the angular location of the target from the phase difference signal.

  • Patent number: 8558734
    Abstract: A ground based avian radar receive antenna is implemented using a vertically oriented offset parabolic cylindrical antenna. The desired azimuth beamwidth is determined by the width of the parabolic cylinder reflector surface and the desired elevation beamwidth by the height of the parabolic cylinder reflector surface. A vertical array of antenna elements is mounted along the vertical focal line to provide electronic scanning in elevation. Low sidelobe levels are obtained using tapered antenna element illumination. Low cost modular construction with high reflector accuracy is obtained by attaching a thin metal reflector to thin ribs machined or stamped in the shape of the parabolic cylinder reflector surface. The antenna is enclosed in a radome and mechanically rotated 360 degrees in azimuth.
