UWB SHORT PULSE RADAR

摘要

A transmission unit emits a short pulse wave satisfying a predetermined spectrum mask from an antenna to a space. A reception unit receives a reflected wave of the short pulse wave from an object existing in the space. According to an output signal from the reception unit, a signal processing unit analyzes the object. The transmission unit includes a pulse generator for outputting a pulse signal of a predetermined width at a predetermined cycle and a burst oscillator for receiving the pulse signal outputted from the pulse generator, performing oscillation for a time corresponding to the width of the pulse signal, and outputting the short pulse wave. The pulse signal width, frequency, and the oscillation frequency of the burst oscillator are set so that the main lobe of the spectrum of the short pulse wave is substantially entirely included in the range from 24.0 to 29.0 GHz in the predetermined spectrum mask and a radiation power density for the RR radio emission-inhibited band of the predetermined spectrum mask is lower than the radiation power density of the peak of the main lobe by 20 dB or more.
