参考阵元可自适应调整的阵列天线抗干扰方法

针对导航接收机抗干扰阵列天线在某些干扰来向存在抗干扰效果减弱的问题,建立了基于功率倒置算法的阵列信号处理模型,提出一种参考阵元可自适应调整的阵列天线抗干扰方法.以四阵元均匀圆阵为例进行了仿真验证,仿真结果表明,相比于参考阵元固定的功率倒置算法,此方法能够很好地解决部分干扰来向抗干扰效果减弱的问题.

Anti-jamming Method of Array Antenna with Adaptive Reference Element

This paper focuses on the issue that the anti-jamming performance of array antenna of navigation receivers is degraded when interferences come from some specific incident angles.In this paper,a signal processing model for analyzing the phenomena is established based on the Power-Inversion algorithm.An anti-jamming method of array antenna with adaptive reference element is proposed.Simulation evaluation is carried out with a model of uniform circular array of four elements and its result shows that compared with traditional method of Power-Inversion algorithm,the proposed method can well solve the problem of performance degradation which happed with some specific incident angles of interferences.
