摘要
提出了将波束成形技术应用于超短波电台,以提高天线增益和系统抗侦收能力。介绍了波束成形技术的原理,仿真了波束成形方向图,设计了6单元阵列天线、6通道射频电路和基带波束成形器,实现了采用波束成形的超短波电台。并对样机的发射波束成形方向图进行了测试,结果表明超短波电台能够采用波束成形技术,并具有很广的应用前景。
The beam forming technique is used in the UHF radio for improving antenna gain and system anti-interception.The theory of beam forming technique is introduced and the antenna pattern is simulated.The 6-elements array antenna,the 6-channels RF circuit and the baseband beam former are designed respectively.The VHF radio with beam forming technique can be acheived.The antenna patterns of beam forming are measured.The result demonstrates that the beam forming technique can be used in the VHF radio with wide application in the future.
