摘　　要：幅相一致性是单脉冲体制相控阵雷达的重要指标,其对雷达测角精度影响很大。采用虚拟仪器技术、自适应处理技术设计了基于PXI总线的幅相一致性测试模块,实现了幅相一致性的快速同步自动测试。试验结果表明,该模块在测试精度、测试方便性和实用性方面与专业矢量电压表测试结果相当。对雷达性能测试能力的提高具有很大的实用价值和指导意义。The identity of amplitude and phase in mono-pulse phase array radar is a very important performance to level a radar receiver. A test module for the identity of amplitude and phase based on PXI bus is designed by using virtual instrument and adaptive processing technology, which realizes automatic test for identity of ampli- tude and phase. The result compared with HP8508 shows that the precision, convenience and practicability of the module are comparative with professional instruments.
