摘　　要：对于飞行试验中规划的通信链路,论文首先介绍了短波通信的最高可用频率预测方法。然后,利用REC533预测了最高可用频率,并与人工选频结果进行了对比分析。最后,进行了仿真验证,仿真结果表明REC533预测的最高可用频率值与人工选频结果在频率变化趋势上保持一致,相对偏差在20%左右。REC533预测的最高可用频率,可用于指导实际频率选择,已广泛应用于各种机载平台。For the planned communication link of flight test,this paper firstly introduces predict methods of the maximum us⁃able frequency(MUF)in HF communication.Then,REC533 is adopted to predict the MUF and the predicted value is compared with the results of manual frequency selection.Finally,the simulation has been done.The simulation results show that the predicted value is consistent with the manual frequency selection result and the relative deviation is around 20%.The MUF predicted value based on REC533 can guide actual frequency selection which has been widely applied to the airborne platforms.
