摘　　要：高轨卫星干扰源定位具有覆盖范围广、性能稳定的优势,是无线电监测的重要手段。然而,卫星干扰源定位的误差主要由定位构型决定,目前鲜有有效算法计算最优轨位。针对这一问题,提出了基于遗传算法的高轨卫星干扰源定位构型优化方法。首先推导了卫星时差定位的几何稀释度模型,并将几何稀释度作为遗传算法的适应度函数,然后基于遗传算法设计了轨位设计中的编码、适应度、选择等原则。最后获得了基于遗传算法的轨位设计结果。仿真试验和实星数据处理验证了所提方法的有效性。High-orbit satellite interference source localization has the advantages of wide coverage and stable performance,which is an important method for radio monitoring.However,the location error of the satellite interference source is mainly determined by the configuration of the satellites,and there are few effective algorithms to calculate the optimal orbit configuration.Aiming at this problem,a satellite configuration optimization method of high-orbit satellite interference source location based on genetic algorithm is proposed.First,the geometric dilution of precision(GDOP)model of satellite time difference localization is derived,and the GDOP is used as the fitness function in the genetic algorithm.Next,based on the genetic algorithm,the principles of coding,fitness,and selection in the configuration optimizing are designed.Finally,the results of the configuration optimizing are obtained.Simulation results and real-star data processing verify the effectiveness of the proposed method.
