摘要
杆天线和接收机之间的同轴电缆产生的耦合效应难免会增加电场测量的不确定度。通过采用光纤技术和集成数字接收机的创新方案替代原有杆天线9 k Hz^30 MHz的测试布置,恰好可消除同轴电缆产生的耦合效应。这种方案可在民用、军用和汽车的杆天线测试中应用。
It's commonly known that the coaxial cable connecting a rod antenna to a receiver does provide coupling effects fatally increasing E-field measurement uncertainty. The scope of this article is to introduce an alternative and innovative solution adopting the benefits of both fiber optic technology and integrated digital receiver design for exactly eliminating those effects caused by coaxial cables in all civil, military and automotive applications adopting the rod antenna for measuring the electric field in the range of 9 kH z^30 MHz.
