摘　　要：极化是描述电磁波的重要参量,为了达到在电子对抗活动中能有效正确选择极化方式的目的,通过诱骗试验中极化方式的选择,得出水平目标会产生竖直方向的偏角,偏离的角度与极化工作方式紧密相关的结论。做了GPS干扰中极化方式选择的实验,获得了在远距离对弹载GPS实施干扰,垂直极化较圆极化好,而圆极化较水平极化好的结果。Polarization is an important parameter to describe the electromagnetic wave. In order to correctly choose the polarization mode in electionic countermeasure （ECM） activities, the conclusion that the deviation angle in vertical direction of a horizontal target is closely related to the polarization working mode is proposed by the selection of the polarization mode in a luring test. The polarization selection experiment for GPS jamming was performed, which successfully realized the interference for the missile-borne GPS in long-distance missile. The exeriment shows that the vertical polarization is better than circular polarization, and the circular polarization is better than horizontal polarization.
