According to a variety of complex target power spectrum,structure function and characteristic function and boundary conditions we have analyzed with many body quantum field theory,such as approximate method for analyzing electromagnetic scattering, dielectric constant of dielectric rough surface biostatic scattering effects and obtained scattering coefficient,FDTD method solves the absorbing boundary,connection and outside boundaries to deal with the problem,we use reciprocity and the equivalence principle to design filter circuit,the particle swarm optimization ( PSO) algorithm,the integrated use of Bezier formula. The noise is eliminated,and the improving the ability of the radar warning. Which has good theoretical significance? Is the theoretical analysis of the design and performance of the radar antenna.
