Intelligent Antenna and Adaptive Digital Beam Forming Technology

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.
