Abstract
Interference suppression is an important research topic in radar signal processing. Distributed array radars have strong interference suppression abilities, which can solve the problem of main-lobe interference suppression. The interference suppression performance of the distributed array radar is affected by array configuration and non-ideal factors. This paper studied the influence of array configuration and non-ideal factors. The impact of array configuration elements, including the distribution of the positions of arrays, the ratio of the area of the main array to the auxiliary array, and the baseline length of the distributed array, on interference suppression performance was studied through simulation analysis. The influence of non-ideal factors, including amplitude and phase errors, time synchronization errors, and auxiliary array beam pointing errors, on interference cancellation performance in different interference scenes was studied by simulations.
