  • Publication number: 20190271776
    Abstract: A radar system has different modes of operation. In a method for operating the radar system, at least one of one or more transmitters are configured to transmit modulated continuous-wave radio signals, while at least one of one or more receivers are configured to receive radio signals. The received radio signals include the transmitted radio signals transmitted by the one or more transmitters and reflected from objects in the environment. The method further includes selectively modifying an operational parameter of at least one of the transmitters or at least one of the receivers. The selected operational parameter is modified to meet changing operational requirements of the radar sensing system.

  • Publication number: 20190235050
    Abstract: A radar sensing system includes a transmitter and a receiver. The transmitter is configured for installation and use in a vehicle and configured to transmit radio signals. The receiver is configured for installation and use in the vehicle and configured to receive radio signals that include the transmitted radio signals transmitted by the transmitter and reflected from objects in an environment. The receiver includes a plurality of inputs and a plurality of low noise amplifiers (LNAs). Each input of the plurality of inputs is communicatively coupled to a corresponding LNA of the plurality of LNAs. The plurality of LNAs are co-located, and respective outputs of the plurality of LNAs are all directly coupled together at a connection point.

  • Patent number: 10261179
    Abstract: A radar system has different modes of operation. In one mode, the radar operates as a single-input, multiple output (SIMO) radar system utilizing one transmitted signal from one antenna at a time. Codes with known excellent autocorrelation properties are utilized in this mode. At each receiver the response after correlating with various possible transmitted signals is measured in order to estimate the interference that each transmitter will represent at each receiver. The estimated effect of the interference from one transmitter to a receiver that correlates with a different code is used to mitigate the interference. In another mode, the radar operates as a multi-input, multiple-output (MIMO) radar system utilizing all the antennas at a time. Interference cancellation of the nonideal cross-correlation sidelobes when transmitting in the MIMO mode are employed to remove ghost targets due to unwanted sidelobes.

  • Publication number: 20190094353
    Abstract: A radar system processes signals in a flexible, adaptive manner to determine range, Doppler (velocity) and angle of objects in an environment. The radar system processes the received signal to achieve different objectives depending on one or more of a selected range resolution, a selected velocity resolution, and a selected angle of arrival resolution, as defined by memory requirements and processing requirements. The system allows improved resolution of range, Doppler and/or angle depending on the memory requirements and processing requirements. The system also adapts to changing environmental conditions including interfering radio signals.

  • Publication number: 20170115377
    Abstract: An integrated circuit (IC) is provided with a plurality of diode based mm-wave peak voltage detectors (PVD)s. During a testing phase, a multi-point low frequency calibration test is performed one more of the PVDs to determine and store a set of alternating current (AC) coefficients. During operation of the IC, a current-voltage sweep is performed on a selected one of the PVDs to determine a process and temperature direct current (DC) coefficient. A peak voltage produced by the PVD in response to a high frequency radio frequency (RF) signal is measured to produce a first measured voltage. An approximate power of the RF signal is calculated by adjusting the first measured voltage using the DC coefficient and the AC coefficient.

  • Patent number: 9379798
    Abstract: The present disclosure relates to a modulation circuit and a method for suppressing energy content of spectral side lobes caused by high-frequency content present in a baseband signal, with the energy content of the spectral side lobes being outside an intended operational bandwidth in a modulated radio-frequency signal. An example circuit is configured to: receive a digital baseband signal, feed the digital baseband signal to a first and a second signal path, with the first signal path comprising a first mixer and the second signal path comprising a delay circuit and a second mixer. The first mixer and the second mixer may receive a same local oscillator signal, and may respectively provide a first radio-frequency signal and a second radio-frequency signal that are delayed with respect to each other. The example circuit is further configured to generate an output radio-frequency signal by combining the first and second radio-frequency signals.
