摘　　要：由于高空平台不可能静止驻留在空中,平台打转、摇摆等状态就会对HAPS(High Altitude Platform Sta-tions)通信性能产生关键影响.目前的研究都处在假设平台稳定或调整波束指向能够补偿由于高空平台移动造成的剩余指向误差,存在很大的局限性,不能真实反应实际情况.本文通过建模把平台的不稳定性带来的影响反应到无线链路上,解决平台不稳定性等造成收发信号随机变化大而无法通信或通信质量差的问题.并通过仿真分析验证本文提出模型的正确性.Obviously the HAP doesn＇t keep stationary all long and the HAP state of mtalion and swing will impact the per formance of HAPS communication seriously. By far, all the research work assumed that the high allimde platform is stationary and offset caused by movement of the high altitude platform is compensated. Therefore traditional method can not resolve the problems caused by the instability of high altitude platform and effects on the performance of HAPS communication by instability of high alti- tude platfoma are researched profoundly. A wireless link model which reflects the states of HAP is proposed and the problems caused by the instabih＇ty of high altitude platform are resolved. Lastly the validity of the model proposed uhis paper is proved by numerical analysis and simulation.
