赋能通信技术原理及应用展望
|
摘要
针对VHF/UHF频段电台仅能视距通信的应用局限,提出了一种基于对流层散射传播体制的赋能通信技术,并对其原理进行了介绍。该技术在不改变现役VHF/UHF电台硬件结构的前提下,通过建立赋能站和加载对流层散射通信波形,可以在VHF/UHF电台与赋能站之间实现可靠的超视距通信。通过理论分析、信道特性试验以及通信试验证实了该技术的可行性。最后对该技术的应用前景进行了分析。对实现多个被动传感器的优化选择和合理布站,提高目标定位精度有一定的理论和实际意义。
The VHF/UHF radio station can only be used for LOS communication.In view of this limitation,this paper proposes an adding-energy communication technology based on troposcatter propagation system,and introduces its principle. This technology can implement reliable BLOS communication between VHF/UHF radio station and adding-energy station by establishing adding-energy station and loading troposcatter communication waveform without changing existing VHF/UHF radio hardware structure.The validity and feasibility of the scheme are proved by theoretic analysis,channel characteristics and communication experiments. In the end,the application vision of the proposed technology is analyzed.
