Digital array radar (DAR), flexible and adaptive interference suppression with waveform such outstanding advantages, will become the inevitable choice of high performance, multi-function radar in the future. Digital T/R module as the key components of digital array radar, quantity is numerous, how effectively to complete digital T/R module automatic test performance indicators, is a research and development, production, integrated security and maintenance problems must be solved in wartime. This article is set in a tracking the development of the guidance radar, automatic test system of digital T/R combination were studied. First introduced the combination of digital T/R composition and basic working principle, the technical requirements of automatic test system are presented, based on the completed test system hardware and software design, circuit design, function implementation. The test system is mainly by the test tooling board, test software, including the FPGA program and computer VC two parts), test equipment, etc. Before finally, introduced the DBF system integration simulation T/R modules, ten channels to send and receive radio circuit, software and system integration digital T/R after the combination of the performance of automatic test system and test results. Design of automatic test system can effectively improve the efficiency of a single module, circuit and the combination of the test.
