摘　　要：为解决机载自卫对抗系统的动态性能检测需要在长时间、高密度的雷达对抗环境信号进行,现有的仪器设备因数据存储空间的限制,无法满足长时间、高密度的脉冲信号的需求。通过建立对抗环境中主要雷达体制信号的数学模型;基于R&S Pulse Sequencer软件及雷达模拟器软硬件实验平台上,通过特殊体制雷达信号库的二次开发,自定义生成信号脉冲描述字(pulse description word,PDW)的方法,进行雷达对抗环境仿真。仿真结果表明,建立的信号模型具有合理性及有效性,生成信号的方法可支持长时间、高密度雷达对抗环境的模拟,具有较高的应用价值。The dynamic performance detection of airborne self-defense countermeasure system needs to be carried out in the radar countermeasure environment signal with long time and high density,however the existing instruments and equipment cannot meet the requirements of the pulse signal with long time and high density due to the limitation of data storage space.A mathematical model was established to counter the main radar system signals in the environment.Based on the R&S Pulse Sequencer software and radar simulator software and hardware experimental platform,through the secondary development of a special system radar signal library,the method of generating a signal pulse description word(PDW)could be customized to simulate the radar countermeasure environment.The simulation results show that the established signal model is reasonable and effective,and the signal generation method can support the simulation of long-term and high-density radar against the environment,so it has high application value.
