Design of the automatic test system of active T/R module

Active array radar (DAR) is a kind of phased radars, which utilizes beam-forming technique both in receiving and transmitting. Active T/R module is a key technique in the next generation of T/R modules for active array radar. In order to realize the automatic test of the active T/R modules, the advanced modern automatic test system (ATS) is built based on GPIB bus. The principle of the ATS for the active T/R module is introduced. The composition and structure of the ATS is described and the designing method of the hardware and software is discussed. The measurement results of the ATS verify that the design of the ATS is reasonable, because its performance is stable and the efficiency of the active T/R module test increases by using it.
