Algorithms for optimal processing of antenna array (AA) signals against the background of a complex of wideband and narrowband interferences are investigated. When narrowband and wideband interferences act simultaneously, there is a degradation in AA, possibly due to the distribution of spatial and temporal processing resources for effective interference suppression. The analysis of the optimal signal processing algorithm against the background of interferences is carried out according to the criterion of the maximum signal-to-interference ratio. The results of signal processing depending on the value of spatial and temporal correlation of interference were obtained and analyzed. The comparative characteristics of the interference complex suppression are given, showing the effectiveness of the linear signal processing algorithm in different conditions.
