Abstract The multiresolution time domain (MRTD) is researched and utilized to analyze the electromagnetic scattering of a target, in order to illustrate its superiorities and advantages. First of all, the paper employs the Daubechies-wavelet, which is compact support, to be the basis, derives the strict calculation formula systematically, while analyzes its dispersion characteristic and the absorbing boundary condition-generalized perfectly matched layer (GPML). Then this algorithm is used to analyze the electromagnetic scattering of a material sphere. At last, the result can be simulated, which is the material spherepsilas radar cross section (RCS) of two-dimension and three-dimension, furthermore, compared with other electromagnetic algorithms. With the same requirement of precision, MRTD not only has the good dispersion characteristic, but also uses only half of the irregular cells to the finite difference time domain (FDTD), meanwhile, the calculation rate can be improved nearly 3 times and it makes the utilization of memory and CPU less. According to the result of analysis, MRTD demonstrates lots of advantages and superiorities in analyzing the electromagnetic scattering problems.
