Paper Abstract

The effects of phased errors, such as piston errors, tilt errors, and focus errors, on beams combination in synthetic aperture systems (SAS) are analyzed based on the experiments conducted by Hu Zhiping et al. (1989, 1990) on beam control of SAS in vacuum and on a numerical simulation. The physical models of the phase control of different phased errors in SAS are presented, and a computer simulation of the beams control in SAS is performed via the FFT computational methods. The result are presented in form of three-dimensional graphs.
