【摘要】 简述自适应天线阵的工作原理，并根据GPS接收机应用的高灵敏度、动态范围大以及接收天线阵元数目不宜过多的特点，研究了在大功率阻塞式干扰的情况下，功率倒置圆阵的性能，计算机模拟结果表明：使用功率倒置自适应圆阵适合于GPS抗干扰情形。更多还原

【Abstract】 This paper relates simple principle of adaptive antenna array. Based on Global Positioning system (GPS) receiver’s traits, which has high sensitivity, large dynamic range but not many receiving antennael elements. In this paper characteristic of power inversion circular array under the condition of strong interference is studied. The results of computing simulation show that the power inversion circular array is adaptable to the case of GPS anti-interference.更多还原
