Adaptive spatial domain anti-interference technology for cylindrical array

This article investigates and simulates the spatial domain anti-interference algorithm of cylindrical arrays. Considering the characteristics of cylindrical arrays, namely that some array elements are unable to receive the interference signal when the interference angle varies, adaptive designs have been implemented for different scenarios. In contrast to the static direction pattern, the adaptive anti-jamming scheme incurs a gain loss of approximately 1-3.9 dB in the desired direction, and the zero depth can stably meet 40dB. In the future, it can be applied to achieve anti-interference in all airspace phased array
