摘　　要：数据采集接口模块是雷达数字阵列模块自动测试系统中的核心模块。在搭建雷达数字阵列模块自动测试系统时,需要设计数据采集接口模块,使其具备快速、准确地完成数字阵列模块的数据采集、及整个自动测试系统的状态控制等功能。文章在详细分析模块的设计需求之后,给出其芯片选型、硬件电路设计、PCB布局。FPGA软件程序依照控制流程采用Verilog语言实现。在某预警雷达模块数字阵列模块自动测试系统中,文章设计的数据采集接口模块完成四个模块数字阵列模块的I/Q采集与上报,本振参考源及开关网络的控制。大批量的数字阵列模块测试表明,该数据采集接口模块功能丰富,性能稳定,具备较高的应用价值。Data acquisition interface module is the core module of automatic test system designed specially for digital array module of a radar. In order to build the automatic test system of radar, It is necessary to design data acquisition interface module. It should have the functions, including data acquisition rapidly and reliably, status control of the automatic test system. Requirements of the system have been analyzed detailedly. It has described that is chip type, hardware circuit design and PCB layout in this paper. FPGA software is programmed according as control flow in Verilog HDL language. Data acquisition interface module designed in the paper have been applied in automatic test system of a early warning radar. It can collect and upload I/Q data of 4 digital array modules. Furthermore, it can contorl local oscillator source and switch net. The actual application proves that the data acquisition interface module is feature-rich, stable in performance and it has a biggish practice value.
