摘　　要：合理的目标模型是现代雷达备受关注的研究课题之一。从雷达的工作原理出发,建立了雷达目标的信号模型。为优化雷达内部算法、提高自身资源的利用率,根据窄脉冲雷达信号具体形式、工作条件和工作模式的特点,对目标模型进行了合理的简化,并按目标分类采用不同的Swerling起伏模型。通过采用Matlab编程模拟,验证了模型的准确性和合理性,通过VC编程模拟雷达P显目标也得到了较为逼真的目标回波。这对于雷达装备的研发和雷达模拟器的研制有一定的借鉴作用。Target signal model is one of the most important topics in modern radar. Target signal model is established on the basis of radar operation principle in this paper. In order to optimize internal algorithm and improve efficiency, target model of narrow pulse radar is simplified based on its signal form, work condition and operation mode. Different Swerling models are adopted according to different target types. The simulation result indicates that the model is exact and logical. Vivid target echo is simulated in radar PPI display by programming with VC. It is useful for radar development and radar simulator manufacture.
