英文摘要	synthetic aperture laser imaging ladar's optical receiver is a heterodyne detect system, so the atmosphere turbulence will affect the phase history of the ladar seriously. unlike in conventional passive optical imaging system, both the wavefront distortion and piston term will decrease the imaging resolution. the distortion of the wavefrom decreases the heterodyne mixing efficient; the piston will cause the pulse-to-pulse phase errors. multi-aperture receiver technology can improve the heterodyne mixing efficient efficiently, but the pattern of multi-aperture should be optimized according to different turbulence intensity. in this paper, we optimize a four-aperture receiver pattern in different turbulence environment. the simulation and experiment results are obtain in our ladar system.
