摘要
为了解决弹载相控阵多通道T/R模块测试项目繁多、效率低下、难于批量生产交付等问题,研制出了一种基于S参数去嵌入修正技术的自动化测试系统。该系统利用矩阵开关切换通道,自动对每个通道的接收、发射项目进行测试。每个通道测试时间小于1 min,发射功率和接收增益不确定度为0.7dB;发射和接收相位测试精度小于2°。
An automatic test system for T/R module of phased array based on S-parameter de-embedding correction technology is developed to solve the problems of various test projects,low efficiency,difficult to batch production.The system switches to the channel by using the matrix switch,and automatically tests on each channel.The test time of each channel is less than one minute.Test precision of transmitting and receiving phase is less than two degrees.
