摘　　要：建立了时变入射波下的衍射层析基本公式。模拟计算了超短脉冲波场入射下其衍射层析的角分布与面分布。初步分析了时变入射波场对衍射层析成像的影响。The basic formula of the diffraction tomography with time-varied incident wave was established. The angle distribution and plane distribution of the diffraction tomography with ultrashort pulse incident wave was simulated. The effect of time-varied wave field on the diffraction tomography was analyzed. The results show when the pulse is not so short, the time-varied wave field does not effect the diffraction tomography, however, when the pulse is very short, it has more serious effect on the latter.
