摘　　要：在雷达对抗系统工作过程中,对表征敌方雷达信号特征的参数进行测量是后续信号处理的前提条件。通过分析某参数测量单元主要的故障模式和薄弱环节,提出了一种提高参数测量单元可靠性的方法。通过优化参数测量单元内的AD芯片的封装结构,新封装结构可兼容原参数测量单元的PCB板设计,降低了AD芯片的失效率,从而提高了参数测量单元的可靠性和环境适应性。通过可靠性试验验证了该方法可行,效果显著。During the work of the EW system,measuring the parameters which characterize the enemy's radar signal is a prerequisite for subsequent signal processing.By analyzing the main failure modes and weakness of a parameter measurement unit,the paper provides a method to improve the reliability of the parameter measurement unit.By optimizing the package structure of analog-to-digital converter inside the parameter measurement unit,we can reduce the failure rate of the analog-to-digital converter,while the new package structure is compatible with the PCB board design of the original unit,so as to improve the reliability and environmental adaptability of the parameter measurement unit.The reliability test verifies the method is feasible and the effect is significant.
