This paper systemically investigates the deprndences of backscattering characteristics on incident angle of the metal surface.In order to distinguish the polarized light from the non-polarized light,which is reflected from the objrcts,this paperdiscusses the encoding and decoding optical system.And usung this system,we can distinguish metal and nonmetal very ell.The principle and method given in the paper are of great academic and realistic effect on the field of missile guidance and target recognition.
