Research on Netted Detection Capability of Low-altitude Targets Based on 5G External Illuminators

This paper researches the netted detection capability of low-altitude targets base on 5G external illuminators, aiming at the surveillance problem of low-altitude non-cooperative targets, represented by unmanned aerial vehicle (UAV). The 5G external illuminators have the characteristics of large bandwidth, short distance between base stations and high target resolution. This paper introduces the netted detection model based on 5G external illuminators by analyzing the characteristics of 5G signals, and studies the positional accuracy and velocity accuracy of low-altitude targets under the layout of multi-source single station by analyzing the detection coverage. The simulation results show that the netted detection base on 5G external illuminators will realize high-precision location and velocity measurement of low-altitude targets.
