摘　　要：分析无人机数据链时延传输特点,研究造成信息传输延迟的因素;在分析数据链传输协议基础上,运用排队论对无人机地空数据链报文传输进行时延建模;基于"当前"统计模型,改进卡尔曼滤波算法对信息传输时延进行补偿。仿真结果表明,该数据传输延迟误差补偿方法与实测数据相比可以明显降低目标测量误差。Analyzes the time delay transmission properties of UAV data link,and studies the factors that cause the delay of information transmission.By analyzing the data link transmission protocol,creates a delay model based on queuing theory for packet transmission of UAV air-ground data link.Based on the ＂current＂ statistical model,the Kalman filter algorithm is improved to compensate the delay of information transmission.The simulation results show that the error compensation method of the data transmission can significantly reduce the target measurement error compared with the measured data.
