摘　　要：针对舰艇防空,提出了一种基于目标运动学特征的目标识别方法。认真分析了现代主要空袭威胁的特征,给出雷达坐标系下高度、速度、加速度、发现距离、连续径向运动等特征的提取方法。在此基础上,建立了三层识别结构,第一层基于点时刻目标高度、速度特征识别战术弹道导弹、武装直升机;第二层基于目标是否作水平方向连续减速运动、连续径向运动等特征识别反辐射导弹、制导炸弹;第三层基于高度和发现距离,采用模糊集和DS理论相结合的方法区分反舰导弹和轰击机等。通过典型目标环境的验证,该方法具有良好的识别效果。A target recognition method is presented based on kinematics characteristics on warship air-defense. After seriously analyzing the characteristics of modern air strike targets, extracting method of height, velocity, acceleration, discover distance and continuous radial motion is given. On that basis, three layer recognition structure is established： layer 1 identifies tactical ballistic missile （TBM） and armed helicopter （AH） according to height, velocity of every moment. Layer 2 identifies anti-radiation missile （ARM） and precision guided bomb （PGB）, according to the feature of horizontal continuous deceleration motion and continuous radial motion. Layer 3 combines fuzzy set and DS theory to identifies anti-ship missile （ASM） and bomb-attacker according to the feature of height and discover distance. Verified by environment of typical targets, this method proposed in this paper has fine effect of identification.
