The Design And Implementation Of Phased Array Antenna Array Test Platform

Recently years, phased array radar technology is in an important stage of rapid development in the world, our country has been in a leading position in the research of radar technology. The phased array antenna array focuses on analysis of the current automatic test system with phased array antenna array test technology research status and development trend. Combing with the present situation of the application of the phased array antenna array test system and the development needs, phased array antenna array testbed is completed.Firstly, the principle of phased array antenna and phased array radar is introduced in this paper. The overall requirements of the test platform design are presented, and the key technology points of the phased array antenna array test platform are summarized.Secondly, according to the overall structure, working principle of phased array antenna array testbed and the hardware system and software system design demand, from the three aspects of the design goal, the overall design scheme of the system is proposed. The host computer software is developed in the.NET programming environment, combing with the use of VISA function library, SCPI instructions, serial port, LAN interface.Thirdly, the hardware platform and software system of phased array antenna array test platform are designed according to the overall design scheme. The hardware platform design includes the selection of test equipment, antenna array receiving state, the design and implementation of the test method of the unit sweep frequency, and the use of the hardware test system. The design of software system includes software architecture design, the communication control layer, data management layer, the design and implementation of human-computer interaction layer and so on.Lastly, the paper explains the phased array antenna test platform structures, during the calibration of the instrument, shows the system software operation process and hardware. At last, the paper summarizes the research content and the prospect of the further promotion of phased array antenna array testbed.
