摘　　要：针对反舰导弹末制导雷达对岛岸附近船舶目标检测困难的问题,提出了基于轮廓像处理理论对岛岸附近目标的检测方法。首先,采用船舶目标轮廓像规则性检测的方法,建立了船舶目标轮廓像模型。同时,运用三种起伏值计算方法对船舶模型进行处理,得到了雷达二维信号图像下船舶目标轮廓像模型的起伏值取值范围。通过模型检测概率仿真,表明该方法能够有效区分船舶目标及岛屿目标,验证了该方法的有效性和可信度,可为提高反舰导弹末制导雷达识别目标能力提供技术参考。In order to solve the problem that it is difficult for anti-ship missile terminal guidance radar to detect the ship target near the island,a method based on the theory of profile image processing is proposed. By using the method of detecting the regularity of ship target profile image,the ship target profile image model is established,and the ship model is processed by three kinds of calculation methods of fluctuation value. The range of fluctuation value of ship target profile image model under radar two-dimensional signal image is obtained. After the simulation verification of the detection probability of the model,it is shown that the method can effectively distinguish ship target and island target,and the validity and credibility of the method are verified,which provides a new technical reference for improving the target identification of anti-ship missile terminal guidance radar.
