  • Patent number: 11921228
    Abstract: This document describes techniques and systems of a radar system with modified orthogonal linear antenna subarrays and an angle-finding module. The described radar system includes a first one-dimensional (1D) (e.g., linear) subarray; a second 1D subarray positioned orthogonal to the first 1D subarray; and a two-dimensional (2D) subarray. Using electromagnetic energy received by the first 1D subarray and the second 2D subarray, azimuth angles and elevation angles associated with one or more objects can be determined. The radar system associates, using electromagnetic energy received by the 2D subarray, pairs of an azimuth angle and an elevation angle to the respective objects. In this way, the described systems and techniques can reduce the number of antenna elements while maintaining the angular resolution of a rectangular 2D array with similar aperture sizing.

  • Patent number: 10871642
    Abstract: Plane Wave Imagers (PWI) directly sense the amplitude and phase of electromagnetic waves and do not require a lens to image a scene. PWI's can also be used in the exit pupil of an afocal lens. PWI's are implemented in CMOS using silicon waveguide technology. Since the wavelength of light ranges from less than one to tens of microns, PWI's fabricated on silicon are essentially flat plates, making a PWI a thin and light structure. A CMOS PWI can operate in the visible, near infrared, short wave infrared, and mid wave thermal spectral bands. Benefits of using a PWI include the ability to achieve large optical aperture performance by digitally processing the outputs of multiple small aperture PWI's that are not necessarily precisely optically aligned. Enhanced scene resolution can be obtained by collecting imagery from several adjacent positions and then digitally combining the digital data into one large dataset.

  • Patent number: 10746868
    Abstract: SAR imaging may be performed with range-resolved reflection data, where a spread-spectrum signal, such as a code division multiple access (CDMA) signal, is transmitted instead of a simple frequency chirp. The reflected spread-spectrum signal may be analyzed to gather range-resolved reflection data. Range-resolved reflection data may be gathered at each angular view. This data may be used to construct a more accurate approximation of the Fourier transform of the desired image than can be done by a conventional SAR approach. The image may be reconstructed from this Fourier transform using Fourier inversion techniques similar to those used in conventional SAR approaches. The range-resolved reflection scheme generally requires somewhat more processing to recover the image as compared with conventional SAR systems, but provides a significantly more stable image with less degradation from effects that plague conventional SAR systems.

    Abstract: Plane Wave Imagers (PWI) directly sense the amplitude and phase of electromagnetic waves and do not require a lens to image a scene. PWI's can also be used in the exit pupil of an afocal lens. PWI's are implemented in CMOS using silicon waveguide technology. Since the wavelength of light ranges from less than one to tens of microns, PWI's fabricated on silicon are essentially flat plates, making a PWI a thin and light structure. A CMOS PWI can operate in the visible, near infrared, short wave infrared, and mid wave thermal spectral bands. Benefits of using a PWI include the ability to achieve large optical aperture performance by digitally processing the outputs of multiple small aperture PWI's that are not necessarily precisely optically aligned. Enhanced scene resolution can be obtained by collecting imagery from several adjacent positions and then digitally combining the digital data into one large dataset.

  • Patent number: 10649075
    Abstract: The present invention is directed to a method for processing radar signals in a distributed array radar that includes a first airborne platform and at least one second airborne platform. Doppler filtered radar return samples are obtained and a weight value is calculated as a function of first clutter signals and second clutter signals. The weight value is employed in a weight vector that is computed, as well, from a steering vector that need not be matched to the target vector. The weight vector is applied to a signal vector corresponding to the Doppler filtered radar return samples. An open loop feedback is implemented and configured to create beam pattern nulls at angles corresponding to the plurality of first interference signals within each of the Doppler bins without substantially tracking a position or velocity of the first airborne platform or the at least one second airborne platform.

  • Patent number: 10536226
    Abstract: Systems and methods for detecting faulty elements in an active planar antenna array of an extremely high frequency (EHF) wireless communication device. A planar antenna array having a matrix of dual-polarization modulated scattering probes is disposed within a near-field region of the antenna under test (AUT). Electromagnetic energy received from the AUT is converted to a complex electrical signal that is modulated by an electrical modulation signal and radiated as a scattering signal. The resulting electromagnetic scattering signal, received and converted to an electrical signal by another antenna, is used in a holographic image reconstruction operation via a backward-propagation transformation to reconstruct the signal spectrum radiated from the surface of the AUT. A comparison of this reconstructed signal spectrum with a reference signal spectrum radiated from the surface of a known good antenna array enables detection of faulty antenna elements within the AUT.

  • Patent number: 10429506
    Abstract: A lateral distance sensor diagnosis apparatus cooperating with a lateral distance sensor in a vehicle includes a travel enabled distance acquisition section and a diagnosis test section. The travel enabled distance acquisition section determines whether the vehicle is estimated to have contact with an object detected by the lateral distance sensor, based on a distance detected by the lateral distance sensor and a present steering angle. When determining that the vehicle is estimated to have contact with the detected object, the travel enabled distance acquisition section acquires a travel enabled distance based on a distance detected by the lateral distance sensor. The diagnosis test section determines that the lateral distance sensor fails to operate normally when a movement distance becomes greater than the travel enabled distance under state where the steering angle is an angle causing the vehicle to have contact with an object detected by the lateral distance sensor.
