It is short the pulse radar of UWB

摘要

The transmission section emits the pulse which fills up the specified spectrum mask from the antenna wave to the space shortly. The reception section the description above which is emitted from the aforementioned transmission section the reflected wave by the object which exists shortly in the aforementioned space of the pulse wave receives processes. The signal processing unit processes the aforementioned object analytically on the basis of the output signal from the aforementioned reception section. The aforementioned transmission section receives the aforementioned pulse signal which is output from the pulse generator and the aforementioned pulse generator which output the pulse signal of specified width at specified period, just width equivalent hours of the said pulse signal oscillate operate, the description above shortly have possessed with the bursting oscillator which outputs the pulse wave. The description above shortly almost the whole of the main lobe of the wave period pulse, entering the range 24.0 - 29.0GHz in the aforementioned specified spectrum mask, at the same time, in order the radiation power density for the RR radio wave discharge forbidden band which the aforementioned specified spectrum mask has radiation power density of peak of the aforementioned main lobe compared to above 20dB to become low, width of the aforementioned pulse signal, period and oscillation frequency of the aforementioned bursting oscillator is set.
