摘要
机载定向通信系统具有通信距离远、传输速率高等优点,而且能够实现载机的隐蔽通信。但由于定向窄波束通信需要波束互锁,而定位数据、姿态信息因素会引起波束指向出现偏差。基于此,建立了定向通信系统的波束指向偏差数学模型,用遗传算法对模型进行求解。给出了不同情况下的波束指向偏差计算结果,并对工程中影响波束指向偏差的因素进行了定性分析。该模型可用于工程中对定向通信系统的波束指向偏差进行评估,根据该结果可进一步进行定向通信的参数设计。
Airborne directional communication system has the feature of far distance and high transmission speed,and can achieve covert communication for the aircraft.However,beam aiming is needed for directional communication,and location data,attitude information will lead to beam pointing deviation.Owing to this,the mathematical model of beam pointing deviation for directional communication system is established,and genetic algorithm is used to solve the model.The calculation results of beam pointing deviation for different cases are given,and the factors of affecting beam pointing deviation in engineering were analyzed qualitatively.This model can be used to evaluate the beam pointing deviation for directional communication system in engineering,and parameters of directional communication can be designed further according to the results.
