To improve the recognition ability of optical imaging system for UAV (unmanned aerial vehicle) target, a synthetic aperture optical imaging system is proposed and designed. Firstly, according to the target size and detection distance the desired parameter indexes of the optical system are confirmed; Secondly, the suitable systematic structure is selected and the initial structure parameters are analyzed; finally, through the optimization of the Zemax software, the spatial resolution of the system at visible wavelength can reach 0.5mrad/pixel, and the detection distance of typical UAV targets in the air achieves 2km. Comparing with the high processing cost of single large optical components in traditional optical system, the design method of the synthetic aperture optical system is feasible, and the processing cost of small aperture optical components can be saved effectively.
