摘　　要：通信感知一体化是5G-A的关键技术之一。本文讨论了通信感知一体化的组网模式、波形设计与感知时隙配比,得到了当前较为成熟的感知技术方案,并详细分析感知指标体系。之后基于独立感知模式的多站点组网和多波形融合组网的真实场景,系统验证了低空无人机近距离和远距离感知的性能,包括感知极限距离、位置精度、速率精度,以及感知对通信的影响,探讨实测逼近理论值,从而得到实际组网感知性能的可行性。The integrated sensing and communication is one of the key technologies of 5G-A.This paper discusses the networking scheme,waveform design and time slot ratio of sensing,obtains the current mature perception technology scheme,and analyzes the sensing system in detail.Then,based on the real scenario of multi-site networking and multi-waveform fusion networking based on the independent perception mode,the performance of low-altitude UAV short-range and long-range perception is systematically verified,including perception limit distance,position accuracy,rate accuracy,and the impact of perception on communication.
