摘　　要：自行弹炮结合防空武器系统火控组网可以保证自行弹炮结合武器在部分分系统失效后仍能具有一定的作战能力;但火控组网信息传递时,被传递信息的量测误差会由于各节点物理位置的不同而引起误差的重新分配,信息传递过程中引入的主从车车体姿态及位置信息的量测误差也会导致信息传递后精度的变化,这种传递误差会影响火控组网中信息传递的精度。根据火控组网的基本形式及原理建立信息传递数学模型,通过对数学模型和信息传递流程的分析建立量测误差传递模型,利用仿真结果对信息传递误差的变化规律进行分析。对信息传递流程中影响误差变化的关键部分建立状态空间模型,通过卡尔曼滤波减小误差的波动,使用滤波后的数据对信息传递流程进行仿真,仿真结果显示该方法减小了传递误差的波动幅度,使精度满足使用需求。The fire control network of a self-propelled anti-aircraft gun and missile system can ensure that the system can still have certain combat capability after some subsystems fail.But when the fire control network transmits data,the measurement error of the transmitted data will lead to the redistribution of the error due to the different physical positions of the nodes,and the measurement error of the body attitude and position data of the master and slave vehicles introduced in the process of data transmission will also change data accuracy after transmission,which will affect the accuracy of data transmission in the fire control network.Based on the basic form and principle of the fire control network,a mathematical model of data transmission was established.By analyzing the mathematical model and data transmission process,a measurement error transmission model was built.Simulation results were used to analyze the change pattern of data transmission.A state space model was set up for the key parts of the data transmission process that affect error change.And the fluctuation of the error was reduced through Kalman filtering.The filtered data was used to simulate the data transmission process.The simulation results show that this method effectively reduces the fluctuation range of the data transmission error so that the precision meets the operating requirements.
