摘要
双星或三星卫星干扰源定位体制中定位成功率受制于邻星的选择和星历的精度。针对上述问题,对利用功率波动的单星定位方法进行了研究。探讨了卫星通信链路中天气情况和大气衰减对信号传播的影响,提出了一种单星无源定位方法,分析了通过皮尔森统计方法得到信号功率波动匹配度的可行性,并通过试验证实了该定位方法的有效性。
The success rate of dual satellite or tri-satellite localization system is limited by the choice of neighboring satellites and the precision of ephemeris.In view of above problems,the single satellite passive localization using power fluctuation is studied.The influence of weather conditions and atmospheric attenuation on signal propagation in satellite communication links is discussed.A single satellite localization method is presented.The feasibility of obtaining matching degree of the signal power fluctuations by Pearson statistical method is analyzed,and the validity of this method is proved by experiments.
