Design and Implementation of Performance Degradation Test System for T/R Module

T/R module is an important part of active phased array radar equipment, and the variation of its performance greatly affects radar technology and tactical indicators. The performance degradation test of T/R module through the test system is an important way to analyze the performance variation of the T/R module. Based on the analysis of the T/R module performance degradation test process, the structure of the T/R module performance degradation test system was designed. The test system platform was designed to solve the problem of noise figure measurement under the automatic test of multiple T/R modules and the switching of cascaded switches. The automatic test software was designed to realize the automatic test of the performance parameters of the T/R modules and the automatic storage of the measurement results. Based on the designed and implemented test system, the performance degradation test of a certain type of T/R module was carried out. The test results show that this test system can automatically complete the test of multiple T/R module performance parameters. It improves the test efficiency and provides a test platform for the performance analysis of T/R modules and active phased array radar.
