Scattering of two-dimension Gaussian rough surface from pulse waves

As the technology of pulse wave is widely applied in microwave and millimeter-wave communication, radar, remote-sensing and other relevant fields in recent decades, the research to the transient electromagnetic fields (also known as time-domain electromagnetic fields) which was related to the pulse wave has been attracting great attention. Therefore, the research to the scattering of rough surface from the pulse wave has significant theoretical meaning and engineering application value. In this paper, by using the basic principle of integral equation method and two-frequency mutual coherence function and angular correlation function of two-dimension Gaussian rough surface, the scattering of rough surface from the delta pulse wave, the Gaussian pulse wave and the rectangular pulse wave are respectively calculated, and the broadening effect of pulse is discussed.
