摘要
针对常见对海侦察雷达目标成像特点及功能的欠缺,提出了一种基于雷达回波序列轮廓像的目标识别方法,对回波序列轮廓像的分离、特征的提取、目标距离及姿态对轮廓像特征的影响等问题展开了具体的讨论,并最终以实验的方式对该方法的可行性和有效性进行了检验。测试结果表明所提出的高阈值目标检测方法可以实现对目标的低错误率检测和准确定位,低阈值检测方法可以实现对目标的准确提取,且两者均具有较强的多目标处理能力和运算实时性。
Aiming at the target imaging characteristic and the function shortcoming of surface reconnaissance radar,this paper presents a target recognition method based on sequencable outline image of radar echo, discusses these problems such as the separation of echo sequence outline image, leature extraction in detail, the influence of target distance and attitude on outline image characteristics, etc. , finally checks the feasibility and validity of the method through the experiment. The test result shows that the high threshold target check method can realize the low error ratio check and precise location to the target, and the low threshold check method can realize the precise extraction to the target, and either of them has stronger multi-target processing capability and real operation ability.
