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 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 radar system with a transmit pipeline transmitting radio signals, and with a receive pipeline receiving radio signals including radio signals transmitted by own transmitters and reflected from objects in an environment, and interfering radio signals transmitted by other radar systems. The receive pipeline provides interference immunity from interfering radio signals transmitted by other radar systems. The transmit pipeline and/or the receive pipeline avoid transmitting radio signals that interfere with the other radar systems. The receive pipeline includes dual polarization receive channels. The interfering radio signals are a different polarization than the radio signals transmitted by own transmitters and reflected from targets in the environment. The receive pipeline provides improved signal handling dynamic range to avoid receive channels saturating at A-to-D converter stage before the radio signal has reached the digital signal processing domain.

摘要： A radar system includes transmitters and receivers configured for installation and use in a vehicle. The transmitters transmit radio signals. The receivers receive radio signals that include the transmitted radio signals reflected from objects in an environment. Each receiver has an RF front end, an analog-to-digital converter (ADC), a digital signal processor, and a controller. The digital signal processor processes the data from the ADC and stores data samples in a buffer. The buffer operates in several modes defined by the controller. These modes include replay mode, loopback mode, quiet mode and throttle mode. By controlling the buffer, the same received samples can be processed in multiple ways to generate information on targets at different ranges and velocities. The buffer is read out and the data is processed further to enable the radar system to determine range, velocity and angle of targets in the environment.

摘要： 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 on a receiver that correlates with a different code is used to mitigate the interference. In another mode, the radar operates as a MIMO radar system utilizing all the antennas at a time. Interference cancellation of the non-ideal cross correlation sidelobes when transmitting in the MIMO mode are employed to remove ghost targets due to unwanted sidelobes.
