研究当动态干扰或同信道干扰存在时,如何提高抗干扰GPS接收机的稳健性问题.在干扰来向上,通过增加微分约束条件,可以将零陷展宽,从而提高其稳健性.主要研究3种稳健自适应抗干扰算法:稳健的功率倒置(PI)算法、加载的稳健功率倒置算法和稳健特征向量投影(EP)算法.3种算法均不需要预知GPS信号和干扰信号的来向等先验信息.仿真结果表明,以上3种稳健算法适用于当干扰源是运动的或同信道干扰源的情形.
This paper studies how to improve the robustness of anti-jamming GPS receiver when dynamic interference or co-channel interference exists.With the increase of differential constraints, Robust adaptive anti-jamming algorithms: robust power inversion (PI) algorithm, robust power-loading inversion robust algorithm and robust eigenvector projection (EP) algorithms. All three algorithms do not require prior knowledge of the GPS signals and the presence of interfering signals Information.The simulation results show that the above three kinds of robust algorithms are suitable for the case when the interference source is a motion or co-channel interference source.
