摘要
单星多波束干扰源定位方法需要在3个以上的同频波束都能接收到干扰源信号的情况下才能实现定位。由于同频波束的数量有限以及干扰源位置的随机性，往往会出现能接收到干扰源信号的同频波束少于3个，或接收增益过低影响定位精度的情况。
【目的】
2
针对只有两个可用波束的定位问题以及进一步提高干扰源的定位精度，提出了通过邻星与主星建立基于多波束天线与到达时间差（TDOA）技术的双星联合定位模型。
【方法】
2
通过建立双星联合定位模型，并联立出定位方程组证明了该模型的可行性。同时，基于定位几何稀疏精度因子（GDOP）对定位模型的接收增益误差、波束指向误差、到达时间差误差以及位置预测误差4个方面进行了定位误差分析，并使用Matlab进行仿真对比。
【结果】
2
仿真实验表明，基于多波束天线与TDOA技术的双星联合定位方法的定位精度明显优于传统的单星多波束定位方法。
【结论】
2
基于多波束天线与TDOA技术的双星联合定位方法利用了TDOA对定位精度影响较小的优势，使其代替部分波束参与到卫星定位中，不仅减少了对定位波束数量的需求，而且减少了测量增益的误差与波束指向的误差，大大提高了定位的精度并提升了可靠性，较单星多波束定位更具优势。
Abstract
The single-satellite multi-beam interference source localization method requires more than three co-frequency beams to receive the interference source signal to achieve positioning. Due to the limited number of co-frequency beams and the randomness of the location of the interference source
it is usually that the co-frequency beams can receive the interference source signal less than three
or low receiving gain
which may affect the positioning accuracy.
【Objective】
2
In order to solve the problem of positioning with only two available beams and further improve the positioning accuracy of interference sources
a dual-satellite joint positioning model based on multi-beam antenna and Time Difference of Arrival (TDOA) technology is proposed through adjacent stars and main stars.
【Methods】
2
In this paper
the feasibility of the model is proved by establishing the dual-satellite joint positioning model and the positioning equations in parallel. At the same time
based on Geometric Dilution of Precision (GDOP)
the positioning error of the positioning model is analyzed from four aspects: receiving gain error
beam pointing error
arrival time difference error and position prediction error.
【Results】
2
The simulation results show that the positioning accuracy of the dual-satellite joint positioning method based on multi-beam antenna and TDOA technology is obviously better than the traditional single-satellite multi-beam positioning method.
【Conclusion】
2
The dual-satellite joint positioning method based on multi-beam antenna and TDOA technology makes use of the advantage that TDOA has less influence on positioning accuracy. Therefore
it replaces part of the beam to participate in satellite positioning
which not only reduces the demand for the number of positioning beams
but also reduces the error of measurement gain and the error of beam pointing with improved positioning accuracy and the reliability. The simulation results indicate that the proposed method is a better positioning method than single-satellite multi-beam positioning.
