  Abstract

Analog Beamforming is a method of creating the beam direction and pattern by changing the amplitude and phase values using phase shifters and signal attenuators connected to each antenna. Analog Beamforming also has the disadvantage that the system complexity and price increase due to the characteristics and cost of each device. The other hand, Digital Beamforming does not use RF devices such as phase shifters and signal attenuators, but controls the amplitude and phase of the signal by digital signal processing at the baseband level. So, hardware configuration of Digital Beamforming is simpler than that of Analog Beamforming. In addition, since the signals of all the antennas can be controlled individually, there are advantages in forming a plurality of beams and processing of signals. In this paper, we designed a system that detect the target directions by using digital Beamforming and monopulse direction detection algorithm and analyzed the performance of the algorithm by applying it to the real system.
