无人机远程通信高密度集成电磁干扰抑制技术
High density integrated electromagnetic interference suppression technology for unmanned aerial vehicle remote communication
摘要
Abstract
In a high-density integrated electromagnetic interference environment,high-density integrated electromagnetic interference suppression technology for UAV(unmanned aerial vehicle)remote communication is studied to enhance the information reliability and effectiveness of UAV remote communication.The energy of high-density integrated electromagnetic interference signals in the UAV remote communication network is estimated,and the electromagnetic interference suppression is realized by means of the adaptive beamforming.The weight coefficient is adaptively adjusted to form a high-density integrated electromagnetic interference signal suppression beam when the incident signal is dynamically changing,and the phase compensation based optimization control method for anti-interference beam pointing is introduced to control the negative impact of frequency jump on electromagnetic interference signal anti-interference beam pointing and optimize the electromagnetic interference suppression effect.The testing results show that after the use of this technology,the information transmission error rate of the UAV remote communication network can reduce from 0.1 to 0.02,and the information reliability and effectiveness of UAV remote communication can be improved.关键词
