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. © 2013 Antenna Society of the Chinese Institute of Electronics.

In this report, we present our recent work on terahertz Cassegrain reflector antenna with compact configuration and directive radiation pattern. The geometrical parameters and electrical performance of the Cassegrain reflector system are calculated and analyzed through folded optics approach, combined with feeding horn design through numerical package simulations. Analytic results of the antenna show high directivity over 50dB, side lobe less than-20dB and beam width of 0.5° from the far field radiation pattern, making the antenna an interesting candidate for high resolution imaging applications as surveillance equipment. © 2013 Antenna Society of the Chinese Institute of Electronics.
