The invention discloses a method for simulating the wide-band electromagnetic scattering property of a conductor target. The method comprises the following steps that the geometric model of the conductor target is built, and
mesh generation is conducted on the surface of the conductor target by a curved surface triangle unit; a
time domain electric field integral equation of the conductor target is determined; a surface induction current in the
time domain electric field integral equation expands through a space CRWG primary function and a time
delay primary function; an expanding surface induction current expression is substituted into the
time domain electric field integral equation, and then the time domain
electric field integral equation in a
discrete form is tested in a time and space mode so as to obtain a
system impedance matrix equation; singularity integrals are eliminated to obtain a sparse expression of a impedance matrix; the equation of the impedance matrix is solved to determine the distribution of the time domain current of the surface of the conductor target, and wide-band electromagnetic property parameters of the target are obtained according to the distribution of the time domain current so as to finish
simulation. The method for simulating the wide-band electromagnetic scattering property of the conductor target has the advantages of being high in
simulation precision, little in required time and low in memory consumption, and has wide application prospect.
