摘要
抗干扰技术在军事通信领域占有极其重要的地位。利用多个全向天线阵元构成的天线阵列能够达到定向天线的效果,通过设计接收滤波器的权向量控制天线波束的指向,从而达到抗干扰的目的。对几种常用抗干扰方法进行了相关的理论分析及仿真试验,其结果对设计智能天线抗干扰系统具有一定指导作用。
Anti-jamming technique plays an important role in the filed of military communication. An antenna array composed of multiple omni-directional antenna elements has a similar effect on a directional antenna. The direction of the beam can be controlled by setting the receive filter weight vector, so that the purpose of anti-jamming can be achieved. Some commonly-used weight vector design methods are theoretically analyzed and simulated. Simulation results can act as a guidance in the design of the anti-jamming system of smart antennas.
