| Abstract: | Based on the linear array antenna system,the basic principle,system composition and implement method of digital beam forming（DBF） are analyzed critically,with the detailed formula.The orthogonal signal correction,channel match correction,beam forming,key technologies and implement methods are described in detail.Combined with engineering practice,the implementation based on the structure of FPGA and DSP is supported,and the working mode and process of DBF system is given.The engineering practice shows that the theory and ways have practicability. |
