Abstract (en)

[origin: WO0248735A1] The invention concerns an ultra broadband radar: It also concerns a modulator in particular for microwave switching over a very short period. The radar comprises a modulator modulating a carrier microwave, said modulator comprising: a microwave mixer (21), means for generating a modulation signal (23). The microwave is inputted on the mixer input and the modulation signal (22) on the other input, the mixer output signal being supplied to the radar transmitting means. Advantageously, the modulation signal can be pulsed and of very short duration. A local oscillator (1) operating as a free oscillator, supplies the microwave to be modulated. The invention is particularly useful for assisting parking of motor vehicles. More generally, it is applicable to all operations requiring low-cost range high resolution detection.
