摘　　要：雷达目标模拟器日益成为雷达整机调试评估不可缺少的测试工具。本文首先简要介绍雷达目标模拟中的几个参量,然后介绍基于DDS+直接调制的多普勒频移模拟方法。该方法具有电路简单、控制灵活等特点,已经在雷达模拟装置中得到了应用。Radar target simulators（RTS） are becoming the necessary test instruments for the evaluation and commissioning of radar system. Firstly, this paper briefly introduced some parameters of the RTS. Secondly, it described the method of Doppler modulation that based on DDS and direct modulator. This method has better performance on both the simple circuit and agile control, and is applied in the RTS.
