  • Patent number: 11906620
    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 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.

  • Publication number: 20230408671
    Abstract: A radar system that uses fast frequency hopping transmit waveform and filter bank receiver consisting of both analog and digital components. The waveform steps discrete frequency tones with short duration and modulates a continuous phase signal on each tone. The frequency hopping patterns are generated using pseudo-random permutation or low-collision method of anti-causal code shifting. To process waveform at radar receiver, a filter bank is used with squelching switches and controls to reduce distortion from strong signal into the receiver. Using the Strong Return Estimator, the timing of the strong signal is used to control the squelching switches.

  • Publication number: 20220236369
    Abstract: 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.

  • 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.
