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.
