摘要： A radar system includes an interference manager. The interference manager detects the presence and the characteristics of interfering radio signals used by other radar systems in proximity. The interference manager also controls the operating characteristics of the radar system in response to the detected interfering signal characteristics. The interference manager selects a time slot, or a frequency band, or a time slot and a frequency band to avoid or mitigate the interfering radio signals from other radar systems.

摘要： A radar sensing system for a vehicle includes transmitters, receivers, a memory, and a processor. The transmitters transmit radio signals and the receivers receive reflected radio signals. The processor produces samples by correlating reflected radio signals with time-delayed replicas of transmitted radio signals. The processor stores this information as a first radar data cube (RDC), with information related to signals reflected from objects as a function of time (one of the dimensions) at various distances (a second dimension) for various receivers (a third dimension). The first RDC is processed to compute velocity and angle estimates, which are stored in a second RDC and a third RDC, respectively. One or more memory optimizations are used to increase performance. Before storing the second RDC and the third RDC in an internal/external memory, the second and third RDCs are sparsified to only include the outputs in specific regions of interest.

摘要： A radar sensing system for a vehicle has multiple transmitters and receivers on a vehicle. The transmitters are configured to transmit radio signals which are reflected off of objects in the environment. There are one or more receivers that receive the reflected radio signals. Each receiver has an antenna, a radio frequency front end, an analog-to- digital converter (ADC), and a digital signal processor. The transmitted signals are based on spreading codes generated by a programmable code generation unit. The receiver also makes use of the spreading codes generated by the programmable code generation unit. The programmable code generation unit is configured to selectively generate particular spreading codes that have desired properties.

摘要： 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 the environment, the current information stored in the radar system, and/or external information provided to the radar system. The system allows improved resolution of range, Doppler and/or angle depending on the desired objective.

摘要： A radar sensing system includes a transmitter and a receiver. The transmitter is configured to transmit a radio signal. The receiver is configured to receive radio signals that include the transmitted radio signal reflected from objects in the environment. The transmitter and receiver are configured to distribute the signal power over frequency so that it is separated from noise and impairments at DC and low frequencies as may be caused by some radar system components which introduce DC offsets and/or low frequency (e.g. flicker) noise.

摘要： A radar sensing system includes at least one transmitter, at least one receiver and a processor. The at least one transmitter transmits a power shaped RF signal. The transmitted RF signal decreases in power over time. The at least one receiver receives a reflected RF signal. The reflected RF signal is the transmitted RF signal reflected from targets in the environment. The reflected RF signal is down-converted and the result provided to the processor. The processor samples the down-converted reflected RF signal during a plurality of time intervals to produce a sampled stream. The different time intervals of the plurality of time intervals will contain different signal levels of RF signals reflected from the targets. The processor also selects samples in the sampled stream over a selected time interval of the plurality of time intervals that is free of RF signals reflected off of near targets.

摘要： 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.
