摘　　要：提出一种基于伪随机码加权的天线阵接收多波束自适应形成新方法。阐述了其工作原理,并以直线阵为例建立了波达方向估计和接收多波束形成算法,给出了伪随机码的选择和使用原则,通过仿真验证了其有效性和灵活性。该方法无需计算加权矢量,只需相关运算即可形成接收多波束,大大提高了波束形成效率,降低了接收机硬件成本,具有较高的工程应用价值。A novel adaptive receiving multibeam forming method for the array antenna is presented based on pseudo-random noise codes weighting. The basic principle of this method is firstly described in detail,and then the Direction of Arrival（ DOA） estimation and receiving multibeam forming algorithms for linear array antenna are established. The simulation tests results prove the validity and flexibility of this method. This method can form the receiving multibeam only by the correlation operation without calculating the weighted vector so that the cost of receiver is greatly decreased,which shows the great value in the project application.
