  • Publication number: 20250199116
    Abstract: A radar device includes a transmit channel for generating a radar signal; and a receive channel for receiving and demodulating echoes; the channels including a shared local oscillator having a frequency that varies as a function of a control signal; a generator of the control signal, so that the frequency of the local oscillator varies in time linearly or stepwise linearly; and means for generating transmit pulses and demodulation pulses; the receive channel including a mixer for receiving as input the echoes and the demodulation pulses and delivering as output a mixing signal, and a low-pass filter for extracting the first harmonic component of the mixing signal and an analog-to-digital converter.

  • Publication number: 20250180725
    Abstract: A device for generating a radar signal includes: a generator of periodically repeated series of trigger pulses having a linearly variable temporal spacing; and an oscillator configured to receive as input said trigger pulses and to generate a train of periodic oscillations in correspondence with each said trigger pulse. The oscillator has a frequency that varies as a function of a control signal. The device includes a generator of the control signal, suitable for varying linearly the frequency of the oscillator from one train of periodic oscillations to another. Furthermore, a radar device includes a transmit channel having such a device for generating a radar signal; and a receive channel configured to receive echoes of the radar signal and to demodulate them synchronously with their generation to extract time-of-flight information therefrom.
