摘　　要：信号和测试定义(STD)标准是面向信号自动测试工程应用的理论基础,但目前该标准中提供的基本信号模型并不能满足雷达告警设备检测需求。针对此问题,依据标准要求扩展线性调频(LFM)脉冲信号类型,并进行信号仿真。基于MATLAB APP Designer工具设计开发测试信号模型加载和实例创建软件,创建信号实例,并通过矢量信号源模拟产生雷达信号,送至雷达告警接收机前端,进行信号的有效性验证。实验证明,扩展的线性调频脉冲信号模型可以满足实际测试需求,为未来雷达信号标准化建模奠定了良好基础。Signal and test definition(STD)standard is the theoretical basis for the application of signal automatic test engineering.However,the primary signal model provided in this standard can not meet the requirements of radar warning equipment testing.The linear frequency modulation(LFM)pulse signal model is expanded according to the standard,and the signal simulation is carried out to solve the problem.The test signal model loading and instance creation software is designed based on the MATLAB APP Designer tool,and a signal instance is created to generate the radar signal through a vector signal source.The signal is sent to the front end of the radar warning receiver to verify the effectiveness of the extended signal model model.Experiments show that the extended LFM pulse signal model can meet the test requirements and lay a good foundation for future standardized radar signal modeling.
