Abstract

The digital beamforming is able to improve the performance of the radar system. The amplitude and phase errors are the unavoidable non-ideal factors in the real system. As a matter of course, such errors would lead to the deterioration of the performance of the antenna array. In this paper, the impact analysis of the amplitude and phase errors on the beam direction for different elements numbers is analyzed. A relationship between the number of elements and the beam direction in the presence of amplitude and phase errors is deduced. The analysis reveals that the real beam direction in the presence of amplitude and phase errors can approximate to the ideal one by increase the number of elements. The simulations show that the real results follow the trend of the deduced ones.
