Digital Beam Forming Analysis Based on Phased Array

Abstract

This paper studies digital beam forming (DBF) methods based on phased array. First of all, the basic principle of DBF is introduced, and the signal direction is controlled through realizing DBF. Secondly, different beam forming methods and their limitations and applications are analyzed. Through the comparison and analysis of different parameters, it is proper to adopt linear constrained minimum variance beam forming method in practical application. Finally, the beam width and zero depth of different parameter beam forming methods are analyzed by simulation.
