Abstract:

Aiming at the requirement of automatic test and data analysis of T/R component of active phased array radar, the hybrid multi-bus automatic system is studied. The performance parameters typical T/R components and the requirements of test instruments and equipment are analyzed, the hardware and software system of Multi-Bus T/R components automatic test system are designed, and the system errors and correction strategies are analyzed. The system adopts the mode of general test instrument combined with special test control unit to test GPIB, LXI, USB bus pulse power meter and noise figure analyzer. Test instruments such as Pulse Power Meter and vector network analyzer are integrated into the console, and the computer is used to control the test process, and the hardware design of automatic test of T/R components is completed. The system software is equipped with the functions of resource management, automatic calibration, automatic testing, manual testing and data management, which effectively improves the system configuration and data analysis and processing capabilities. The test results show that the automatic test greatly reduces the workload, and the error processing method based on the loss data correction can effectively ensure the test accuracy.
