说明：  合成孔径雷达( SAR) 是一种高分辨率成像雷达，可以在能见度极低的气象条件下得到类似光学照相的高分辨雷达图像。 BP算法基于时域处理回波信号，利用脉冲压缩技术实现距离向匹配滤波，方位向分辨率通过沿回波曲线进行相干叠加实现。(Synthetic aperture radar (SAR) is a kind of high-resolution imaging radar, which can obtain high-resolution radar images similar to optical photography under extremely low visibility weather conditions. BP algorithm is based on time-domain processing of echo signal, using pulse compression technology to achieve range matched filtering, azimuth resolution is achieved by coherent superposition along the echo curve.)

5G 的网络架构和业务特征相对于 3G/4G 时代出现了较大变化，对 5G 承载 网提出了挑战性的需求。针对大带宽、超低时延、高可靠、高精度同步、灵活性、网 络切片、智能协同等七大特征，探讨了 5G 承载技术方案，涵盖前传、中传和回传承 载方案，并分别对应有源天线单元（AAU）和分布单元（DU）之间，DU 和集中单元 （CU）之间，以及 CU 和核心网之间的通信承载。(Comparing with 3G/4G, 5G network architecture and service characteristics have changed great|y, which brings cha||enging requirements for 5G bearing network. |n this paper, seven features of 5G are proposed, such as wide bandwidth, u|tra |ow |atency, high re|iabi|ity, high-precision synchronization, f|exibi|ity, network section, and inte||igent cooperation. And 5G bearing technica| proposa|s are a|so discussed, inc|uding fronthau|, midd|ehau| and backhau| which correspond to the bearing network between active antenna unit (AAU) and distributed unit (DU), the bearing network between DU and centra|ized unit (CU), and the bearing network between CU and core network)
