北斗导航卫星定位系统建设对自适应抗干扰技术的应用提出了更高的要求。值得注意的是，从目前北斗导航系统运行情况看，存在的干扰源仍较多，为抗干扰工作带来极大的难题，要求不断完善自适应抗干扰技术。文章对北斗导航系统进行简要概述，分析自适应干扰抑制算法与基于功率倒置算法的应用，并对应用改进算法取得的成效做仿真分析。(The construction of Beidou navigation satellite positioning system puts forward higher requirements for the application of Adaptive Anti-jamming technology. It is worth noting that from now on, The operation of Beidou navigation system shows that there are still many interference sources, which brings great difficulties to anti-jamming work, and requires continuous improvement of Adaptive Anti-jamming technology. This paper gives a brief overview of Beidou navigation system, analyses the application of adaptive interference suppression algorithm and power inversion algorithm, and makes a simulation analysis of the results of the application of the improved algorithm.)
