  • Patent number: 11489255
    Abstract: A phase shifter that includes an RF splitter is disclosed. The RF splitter is arranged so that an RF input signal is provided to, and split over portions of, a feed line that connects an antenna element with a radio transmitter/receiver/transceiver, thus realizing a feed line splitter. Feed line splitters described herein are provided with switches that allow changing a point at which the RF input signal is fed to the feed line, where the switches may be semiconductor-based or MEMS-based switches. The point at which the RF input signal is provided to the feed line to be split defines the electrical path length that the RF energy will travel down each respective path of the feed line splitter, which, in turn, changes the phase shift realized at each output of the feed line splitter. Different antenna elements may be coupled to different outputs of the feed line splitter.

  • Patent number: 11467250
    Abstract: The techniques of this disclosure describe a scalable cascading automotive radar system that generates a common oscillator signal enabling consecutive chirps to be output more quickly and precisely than any previous cascading automotive radar system, thereby reducing phase noise and improving performance. The scalable cascading automotive radar system combines a respective LO signal output from at least two primary transceivers to distribute the combined signals as a common oscillator signal to be input to all the transceivers of the radar system. Thus, settling time and resetting times that otherwise occur between chirps generated by other automotive radar systems are reduced because the common oscillator signal is no longer constrained to a single LO signal from a single primary transceiver.

    Abstract: A method is disclosed for designing a sparse array for an automotive radar. The method moves each of a number of antenna elements to candidate neighboring grid positions starting from an initial random seed placement to iteratively search for a placement of antenna elements that improves upon a cost function. The cost function for each candidate placement may be determined from characteristics of the FFT response associated with the candidate placement. The method may search for a candidate placement with the lowest cost function among the multiple candidate placements based on the random seed placement. The search may be repeated for a large number of random seed placements to find the candidate placement with the lowest cost function corresponding to each random seed placement. The method may compare the lowest cost functions corresponding to the multiple random seed placements to determine an optimized placement having the minimum cost function.

  • Patent number: 11327170
    Abstract: A method and system involve obtaining reflected signals in a radar system using a first one-dimensional array of antenna elements and a second one-dimensional array of antenna elements. The reflected signals result from reflection of transmitted signals from the radar system by one or more objects. The method includes processing the reflected signals obtained using the first one-dimensional array of antenna elements to obtain a first array of angle of arrival likelihood values in a first plane, and processing the reflected signals obtained using the second one-dimensional array of antenna elements to obtain a second array of angle of arrival likelihood values. A four-dimensional image indicating a range, relative range rate, the first angle of arrival, and the second angle of arrival for each of the one or more objects is obtained.

  • Patent number: 11309636
    Abstract: An example radar system includes a transmission array and a reception array, each aligned as a linear array. The radar system also includes a transmitter configured to cause transmission of radar signals having a center frequency by the transmission array. The radar system also includes a receiver configured to receive radar signals having the center frequency that are received by the reception array. The radar system also includes a processor configured to process received radar signals from the receiver, and adjust the center frequency from a first center frequency to a second center frequency. The adjusting of the center frequency from the first center frequency to the second center frequency causes the frequency-dependent transmission radiation pattern of the transmission array to tilt in a first direction and the frequency-dependent reception radiation pattern of the reception array to tilt in an opposite direction from the first direction.

  • Patent number: 11310067
    Abstract: A broadband communication system aboard an aircraft includes a steerable antenna, a modem, and processing circuitry. The processing circuitry determines a region on the ground where sidelobes of the radiated signal power pattern are incident. A regulatory power flux density (PFD) envelope is determined. PFD generated by the sidelobes in the region on the ground is estimated based on the ESD pattern of the steerable antenna and the aircraft altitude, attitude, and location. The processing circuitry determines, based on the estimate of the PFD generated by the sidelobes in the region on the ground and based on the regulatory PFD envelope, a target ESD pattern for the steerable antenna. The processing circuitry further controls at least one of: 1) output power of the modem based on the target ESD pattern; and 2) bandwidth of the data traffic output by the modem based on the target ESD pattern.
