  • 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.

  • 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.

    Abstract: A shared radar and communication system for a vehicle includes capabilities for radar detection and communication with vehicles equipped with similar systems. A transmitter transmits a modulated radio signal that is modulated based upon at least one of a first spreading code and a second spreading code. The second spreading code is defined by a first plurality of information bits. A receiver receives radio signals that include the transmitted radio signals transmitted by the transmitter and reflected from objects in an environment. A control unit is configured to select the first plurality of information bits. The selection of the information bits encodes selected information for transmission via the transmitted modulated radio signal to be received by another radar sensing system.

  • Patent number: 9954955
    Abstract: A shared radar and communication system for a vehicle includes capabilities for radar detection and communication with vehicles equipped with similar systems. The radar system is equipped with pluralities of transmit antennas and pluralities of receive antennas. The radar transmits a signal modulated with spread codes that are information bits. A receiver discriminates the signals sent from own transmitters and multiple reflections to detect objects of interest. In addition, the receiver discriminates signals transmitted from different systems on other vehicles. This requires the receiving system to have knowledge of the codes transmitted by the other vehicle. The receiving system determines the information bits sent by the other vehicle. If multiple radar systems on multiple vehicles use different sets of codes (but known to each other), the multiple systems can create a communication infra-structure in addition to radar detection and imaging.

  • Patent number: 7895411
    Abstract: One embodiment of the invention sets forth a hardware-based physics processing unit (PPU) having unique architecture designed to efficiently generate physics data. The PPU includes a PPU control engine (PCE), a data movement engine and a floating point engine (FPE). The PCE manages the overall operation of the PPU by allocating memory resources and transmitting graphics processing commands to the FPE and data movement commands to the DME. The FPE includes multiple vector processors that operate in parallel and perform floating point operations on data received from a host unit to generate physics simulation data. The DME facilitates the transmission of data between the host unit and the FPE by performs data movement operations between memories internal and external to the PPU.
