Abstract

A frequency-domain pulse design method for ultra wideband (UWB) vehicular radar system is proposed. Morlet wavelet pulses with the diverse dilatation factors are randomly selected as basis ones. By adjusting these parameters such as the dilation and the value of the amplitude spectral, the corresponding power spectral density (PSD) of linear combination pulse is obtained which must match the FCC´s PSD mask as closely as possible and maximize the bandwidth. Then the combination coefficients are directly obtained by the solution of frequency-domain restraint equation group. Simulation results show that the PSD of combination pulse has larger bandwidth than that of single Morlet pulse and complies with the FCC spectrum mask.
