According to the basic principle of near-field scattering measurement of two stations, two-dimensional cylinder is taken as the target to be measured, and the near-field scattering measurements of two stations are simulated by computer. The effect of limited scanning surface and data processing method on the measurement results of near-field scattering from two stations is studied. The width of scanning surface, the distance between scanning surface and the target, the confidence angle and the testing accuracy are summarized This paper gives some useful results, confirms an effective and reliable near-field data processing method, and proposes and demonstrates a principle of selecting the width of the scanning plane.
