摘要

本文提出了一种自适应波束形成保护方案，以实现工作在4.2 - 4.4 GHz的雷达高度计与3.7 - 4.0 GHz的潜在5G蜂窝业务共存。该方案旨在设计一种能够消除指向天空的副瓣的自适应波束形成器，其中权重根据动态环境自适应变化。为了准确模拟雷达高度表接收信号，对雷达高度表系统、5G基站、通信信道和传播环境进行了建模。仿真结果表明，该方案能准确地测量出飞机的高度。

Adaptive beamforming scheme for coexistence of 5G base station and radar altimeter

In this paper, an adaptive beamforming protection scheme is proposed to enable the coexistence between radar altimeter operating in 4.2 to 4.4 GHz and potential 5G cellular services in 3.7– 4.0 GHz. The proposed scheme aims to design the adaptive beamformer capable of eliminating sidelobes directed skywards, where the weights are adaptively changed according to dynamic environment. To accurately simulate the received signal at the radar altimeter, the radar altimeter system, 5G base stations, communication channels, and the propagation environment are modelled. The simulation results describe that the altitudes of the airplane are accurately measured by the proposed scheme.
