摘　　要：为了实现岛岸背景的抑制,提出了一种基于地理信息系统(GIS)的雷达导引头岛岸背景抑制方法。首先通过GIS系统获取预定打击目标附近岛岸的海岸线等数据,然后结合导弹自身的位置和姿态信息,解算出导弹与岛岸的相对态势,最后根据解算出的相对态势控制雷达导引头的搜捕范围,从而实现岛岸回波的抑制。通过雷达导引头在岛岸背景下的试验,验证了所提方法的可行性和有效性。A background suppression method based on GIS is proposed in order to suppress the littoral background. Firstly,coastline of the littoral background near the targets is obtained from the GIS. Secondly,the posture between the missile and the island is calculated by the combination of the position and posture information of the missile and the coastline data. Finally,the search map of the seeker is controlled based on the posture,and the littoral background suppression is achieved. The experimental results show that the proposed method is feasible and effective.
