In response to the application demands for the automatic test system(ATS)of ultra-wideband(UWB)digital receiver subarrays for active phased array radars,a system is designed based on the Matlab software and utilizes LAN interfaces to achieve communication and control be-tween an industrial computer,test instruments,and the subarrays under test,providing a visual and automated testing environment.The ATS reduces manpower and simplifies the complex proce-dures of repeated assembly and disassembly,enhancing the efficiency of testing digital subarrays,and thereby providing crucial technical support for the development and production of radar UWB digital subarrays.
