摘要
相控阵雷达由于阵列天线副瓣偏高容易被电子战系统进行副瓣侦察和干扰。在下一代相控阵雷达的研制中,智能天线已经成为重点发展方向。介绍了智能天线的基本概念、空时联合通道模型,重点阐述了智能天线接收波束形成与发射波束形成的应用。
Because the side lobe of phase array antenna is on the high side, it will be reconnoitred and jammed easily by the electronic warfare system. In the development of the next generation phase array radar,intelligent antenna has become the important development direction. This paper introduces the basic principle,space-time channels models of intelligent antenna ,expounds the application of receiving beam forming and transmitting beam forming to intelligent antenna.
