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 includes transmitters configured to transmit radio signals, receivers configured to receive radar signals, and a control unit. The received radio signals include transmitted radio signals transmitted by the transmitters and reflected from objects in an environment. The control unit adaptively controls the transmitters and the receivers based on a selected operating mode for the radar system. The selected operating mode meets a desired operational objective defined by current environmental conditions. The control unit is configured to control the receivers to produce and process data according to the selected operating mode.

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 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.

摘要： A method for operating a radar sensing system includes configuring a transmitter to transmit a radio signal. A receiver is configured to receive radio signals. The received radio signals include the transmitted radio signal transmitted by the transmitter and reflected from objects in the environment. The method includes with advanced temporal knowledge of the codes used to modulate the transmitted radio signal, using code values of the plurality of codes, and in combination with a bank of digital finite impulse response (FIR) filters, generating complementary signals of any self-interference noise. The method further includes subtracting the complementary signals at one or more points in the receiver prior to the interference desensing the receiver. The radar sensing system further includes a frequency modulated continuous wave (FMCW) interference canceller for detecting the largest interference signals and sequentially cancelling them while signal processing the received radio signals.

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 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.
