Abstract: A novel Gaussian pulse generation method for impulse ultra-wideband(UWB) radar system is presented.The ultra-short pulse generator is designed based on the switch characteristic of the microwave transistor,the transition characteristic of the step recovery diode(SRD),and the charging and discharging process of the capacitor.The software ADS is used to simulate and analyze the pulse generator circuit.The measured results show that the circuitry can generate pulses with amplitude of 4.1V and duration of 400 p...
