摘要

对互耦补偿后的自适应阵列性能作了深入的分析。分析表明

通过对互耦的补偿

自适应阵列能够完全抑制干扰

但是噪声的输出功率随着波束扫描方向的变化而发生变化

导致阵列输出信干噪比(SINR)性能下降。因此

互耦补偿后噪声是影响自适应阵列输出SINR性能的主要因素。仿真结果进一步验证了结论的正确性。

Abstract

The performance of adaptive arrays with mutual coupling compensation was analyzed in detail.It was indicated that the adaptive array was able to suppress interference thoroughly.The output power of noise

however

was influenced by the direction of beam scanning

which caused the degradation of the output signal-to-interference-plus-noise ratio（SINR） of the adaptive array.Therefore

the thermal noise is responsible for degrading the output SINR of adaptive arrays after mutual coupling compensation.The conclusions were further demonstrated by the simulation results.
