This paper is based on the product theorem of the pattern in the radiation problem,the product method of the pattern in the antenna scattering problem is proposed,and based on the defini-tion of the scattering field of the antenna mode item,the separation method of the scattering field of the antenna mode item is proposed.The product method of scattering pattern combined with the theo-ry of antenna scattering field separation forms the calculation method of phased array antenna scatter-ing field proposed in this paper.The calculation method not only realizes the derivation of scattering field from element to array,but also realizes the quantization and separation of antenna mode item RCS(Radar Cross Section).Finally,by analyzing the array factors in the product method of single-station scattering pattern,this paper obtains the optimal array inclination angle to realize the RCS re-duction of phased array antenna.By tilting the antenna array to a certain angle,the RCS reduction of antenna mode item is realized.
