摘要：

The general image relations of electromagnetic sources are presented around a conductor sphere. The general transformations of trigonometric functions and the unit vectors between two coordinates depart from a distance are obtained. The second scattering field for a target is derived in detail. The complex scattering field and the complex RCS are gained respectively. Results show that the electromagnetic interaction of the targets must be calculated as the distance between two targets is small. The second scattering field is small to three order in magnitude to its first scattering field as the distance becomes large. The phase shift of the second field is mainly determined by the target size and the observing position and not affected greatly by its surrounding target and the distance apart. The distortion of a pulse wave is mainly induced by the phase shift of the second scattering field from the particles as the wave propagating through the random discrete medium.
