摘　　要：雷达目标空间状态随时间的变化特性从侧面揭示了的目标的本质,这种目标空间状态随时间呈现的分布特性称之为目标的时间谱,而利用目标的时谱信息(目标的航迹、速度、机动性、空间坐标信息)可以简化(或缩小)待识别目标的范围。用低分辨雷达测量得到的时间谱信息作为特征,采用模糊逻辑规则对五类飞机目标进行分类判决。结果表明:基于时间谱信息的飞机目标分类为低分辨雷达飞机目标识别提供了一个有效的辅助手段。The motion state of the aircraft target changes with the time. This characteristic is called registration of target. It partially reveals the essence of the target. With the registration information(track, velocity, maneuverability, coordinate), we can simplify (or reduce) the range of the targets to be identified. Registration Information is used in this paper to classity five kinds aircraft targets by fuzzy logic principles in this paper. The results prove that it is a helpful method to identify aircrafts for low-resolution based on registration information.
