According to the special demand of antennas for the impulse radar in detecting the concealed target,the transmitted-received antennas have been designed and optimized.The Vivaldi antennas are designed based on the analysis and the summary of the traditional Vivaldi antenna＇s design method.And in the time and frequency domain they are analyzed and evaluated combined with the needs of impulse radar.A new model of Vivaldi antenna using certain loading form is designed based on the genetic algorithm.This new model can strongly support the experiment for detecting the concealed targets with an efficient inhibition of the pulse tail.
