摘要
随着数字阵列雷达在空战领域的广泛应用,作为其核心组件的数字阵列模块的测试需求日益迫切;传统手动测试方法难以满足其高精度、快速化的维修检测要求,故对上位机测试软件和硬件资源进行集成,实现了DAM自动测试所需四路时钟激励信号的相位同步设计,摆脱了外部本振参考源分机的刚性约束;该设计实验表明,自动实现了发射脉内信噪比、接收信噪比等测试的序列执行、数据采集、处理分析全过程,将单模块测试时间缩短至十分钟级别,且测试结果的一致性与可靠性显著优于传统手动测试方法;目前该设计已正式投入某型数字阵列模块的测试流程中,为实验调试、外场保障等应用场景提供了重要的支撑。
With the widespread application of digital array radar in air combat,the testing requirements for digital array modules—its core components—have become increasingly urgent.Traditional manual testing methods struggle to meet the high-precision,rapid repair and inspection demands.By integrating the host computer's testing software and hardware resources,the phase-synchronized design of four clock excitation signals required for DAM automatic testing was achieved,eliminating the rigid constraints imposed by external local oscillator reference sources.Experiments demonstrate that the automated execution of testing sequences,data acquisition,and processing analysis for metrics such as transmit pulse SNR and receive SNR has been fully realized,reducing single-module testing time to the ten-minute level.Moreover,the consistency and reliability of test results significantly outperform traditional manual methods.This system has now been officially deployed in the testing process of a certain type of digital array module,providing critical support for applications like experimental debugging and field maintenance.
