  • Broadband radar and modulator, in particular for microwave switching over a very short period
    Patent number: 7161526
    Abstract: The present invention relates to an ultrawideband radar. It also relates to a modulator, in particular for switching microwaves over a very short duration. The radar includes a modulator modulating a carrier microwave, this modulator including a microwave mixer means for generating a modulation signal. The microwave enters on one input of the mixer and the modulation signal on the other input of the mixer, the output signal from the mixer being provided to the transmission means of the radar. Advantageously, the modulation signal may be pulsed and of very short duration. A local oscillator, operating as a free oscillator, provides the microwave to be modulated. The invention applies in particular in respect of aiding the parking of motor vehicles. More generally, it applies in respect of all applications which require low-cost high distance resolution radar detection.

  • Receiver for a frequency-shift-keying, continuous-wave radar
    Patent number: 6618449
    Abstract: A receiver of a frequency-shift-keying, continuous-wave radar comprises at least sampling means taking real samples of the signals in each reception channel and extrapolation means, the extrapolation means producing fictitious samples synchronous with the real samples, the reception signals being formed out of real samples and fictitious samples. Application especially to radars fitted into automobiles.

  • Low-cost radar with high-resolution imaging
    Patent number: 6429805
    Abstract: A radar including a plurality of reception antennas corresponding to a plurality of homodyne reception channels, and a transmission antenna positioned with respect to the plurality of reception antenna such that a distance between the transmission antenna and each consecutive reception antenna of the plurality of reception antenna respectively increases from one reception antenna to the next. Also included is a beam-formation mechanism associated with the plurality of reception channels for receiving a reception signal from each of the homodyne reception channels. Further, a spacing between each reception antenna is set so as to orient a homodyne leakage in a direction located in an angular zone of space not processed by the radar.
