Low Altitude Target Detection Technology Based on 5G Base Station

With the rising of the civil UAV (Unmanned Aerial Vehicle) industry and the opening of low-altitude airspace, UAVs are frequently used for privacy snooping, terrorist attacks and similar activities, which greatly harm people's safety and social security. However, in the complex urban environments, traditional low-altitude target detection methods are difficult to effectively detect small low-altitude targets which have small size and low speed. With the advent of 5G, intensive networking of 5G base station makes 5G signal is the most abundant resources of electromagnetic in the city, using 5G as external illuminator signal can not only realize the effective detection of low altitude small target, also save the cost, reduce the impact on the urban electromagnetic environment such as the radar, promoted the radar communication integration. Based on the above research background, this paper mainly studied the low altitude target detection scheme based on 5G base stations which is applicable for urban environment. This scheme using 5G base stations as radar transmitters, 5G signal as radiation source, set up the receiver receives the forward scattering signals from the target in order to achieve low altitude target detection and imaging. This paper systematically discusses the feasibility and advantages of 5G signal used as radar radiation signal, studies its radar performance, and the simulation proves its superior speed resolution and range resolution. It provides theoretical basis and support for the application of low-altitude airspace accurate detection and so on, and pushes forward the integration process of radar communication.
