We　focus　on　photonic　generation　and　transmission　of　microwave　signals　in　this　work.　Based　on　dual-pumped　stimulated　Brillouin　scattering,　a　single-sideband　(SSB)　optical　signal　with　high　sideband　rejection　ratio　is　obtained.　Combined　with　a　phase-modulated　optical　carrier,　an　arbitrarily　phase　coded　microwave　signal　is　generated　after　photoelectric　conversion.　The　SSB　modulation　can　eliminate　the　fiber-dispersion-induced　power　dispersion　naturally,　and　the　phase　modulation　of　the　optical　carrier　can　achieve　arbitrary　phase　encoding　and　suppress　background　noise.　The　proposed　scheme　can　achieve　both　generation　and　anti-dispersion　transmission　of　arbitrarily　phase　coded　signals　simultaneously,　which　is　suitable　for　one-to-multi　long-distance　radar　networking.
