摘　　要：提出了一种将雷达目标识别方法与具体战情相结合的方法,并通过该方法对弹道目标雷达宽带识别方法进行了仿真与评估。仿真了空间目标飞行弹道后,通过坐标变换得到设定战情下的弹道目标雷达视线角。然后结合室内缩比模型静态测量数据,得到设定战情下弹道目标高分辨距离像。对仿真得到的三类弹头类目标进行识别,并分析了雷达带宽、信噪比、观测次数对识别性能的影响。A novel approach was proposed, in which the method of radar target recognition was studied when the actual scene of recognition was taken into account. By this approach, the method of ballistic target recognition using wideband was simulated and assessed. After the ballistic trajectory in midcourse was simulated, the aspect angles of warhead target were calculated in assumed scene by coordinate transformation. Then, the corresponding high resolution range profiles （HRRP） of the target were obtained according to the static measurement data. Lastly, the HRRPs of three kinds＇ analogous missile target were used for identification and the recognition performance was analyzed when recognitions conditions were changed.
