    摘要:

    無(wú)人機飛行環(huán)境中含有大量噪聲及干擾信號,無(wú)法確認多個(gè)無(wú)人機目標偵測遙控信號的頻段與參數,識別誤差和識別速度受限,為快速獲取無(wú)人機目標位置信息,提出基于偵測遙控信號的無(wú)人機目標位置快速識別方法。計算無(wú)人機遠程遙控控制量,設置無(wú)人機遙控信號量化生成過(guò)程,采用加權平均法,獲得初始生成的高質(zhì)量的無(wú)人機遙控信號,分析無(wú)人機遙控信號的載波波形,構建無(wú)人機目標位置坐標系,權衡和融合各個(gè)無(wú)人機飛行環(huán)境特征向量的權值,計算無(wú)人機目標與地標距離之間的距離參數,求解地面遙控信號發(fā)射姿態(tài)角,應用特征匹配度檢測方法,快速識別無(wú)人機目標位置。實(shí)驗結果表明,綜合單一目標和多目標實(shí)驗場(chǎng)景后,識別誤差分別降低了6.2m和9.3m,同時(shí)位置識別速度得到明顯提升。

    Abstract:

    The drone flight environment contains a large amount of noise and interference signals, making it difficult to confirm the frequency band and parameters of multiple drone target detection and remote control signals, resulting in limited recognition error and speed. In order to obtain rapid drone target position information, a rapid drone target position recognition method based on detection and remote control signals is proposed. Calculate the amount of drone remote control control, set up the simulation process of drone remote control signal, use the weighted average method to obtain the initially generated high-quality drone remote control signal, analyze the carrier waveform of the drone remote control signal, construct the drone target position coordinate system, weigh and fuse the weights of various drone flight environment feature vectors, and calculate the distance parameter between the drone target and the landmark distance, Solve the attitude angle of ground remote control signal transmission, apply feature matching detection method, and quickly identify the target position of unmanned aerial vehicles. The experimental results show that after integrating single target and multi target experimental scenarios, the recognition error has been reduced by 6.2m and 9.3m, respectively, while the position recognition speed has been significantly improved.
