Short-pulse radar Uwb

Transmitting section radiates into the space a short pulse waves satisfy the predetermined spectrum mask from an antenna. Receiver receives processing a reflected wave by the object existing in the space of the short pulse waves emitted from the transmitting unit. The signal processing unit based on the output signal from the reception unit, performs analysis processing of the object. And the transmission unit, a pulse generator for outputting a pulse signal of predetermined width at a predetermined period, receives the pulse signal output from the pulse generator, and the oscillation operation by a width corresponding time of the pulse signal, the short and a burst oscillator for outputting a pulse wave. Almost entirely enters the range of 24.0~29.0GHz in the predetermined spectrum mask, and the radiation power density for RR radiating forbidden band having a predetermined spectrum mask main lobe of the spectrum of the short pulse wave There wherein so as to be lower than 20dB than the radiation power density of the peak of the main lobe, the width of the pulse signal, the oscillation frequency of the periodic and the burst oscillator is set.
