We present a linear analysis of two-stream Smith-Purcell Free-Electron Laser (SP-FEL). In this system, two electron-beams with velocity separation pass a rectangular dual-grating. The dispersion relation is derived employing the linear fluid theory and the growth rate is investigated through the numerical solutions. The instability of two-stream is obtained at an optimize separation velocity, and the effects of separation velocity , distance between the dual-grating, groove-depth, groove-width, beams energy on growth rate and bandwidth are studied in detail.
