摘要
单脉冲雷达的测角精度对多通道收发模块的幅相一致性提出了较高的要求,毫米波下变频器是该雷达的一个重要接收部件,本文介绍了一种针对多通道下变频器通道间相位一致性的测量方法,依靠Agilent系列仪器来实现,给出了实测结果和相位补偿方法。结果表明,该测量方法正确,测量精度高,经过补偿的下变频器能够满足单脉冲雷达测角精度的要求。
The effect of phase balance of downconverter on measurement ofmonopulse radar is analyzed,and a method to measure phase consistence of four channels downconverter by Agilent measuring instruments is provided.Measurement results and phase compensation technology are given showing the method is effective on improving angle measurement accuracy.
