Analysis and simulation of narrow band digitally beamformed phased array antenna with null steering

Abstract EN

This paper illustrates the analysis and simulation of narrow band antenna arrays with adapted radiation pattern using digital beamformation.

The technique used for the system is the Shifted Sideband Beamformer (SSB).

This paper analyzes the stages of the receiver and presents a model for simulation.

The SSB was chosen because it exhibits moderate complexity and storage requirement.

Different spatial filters such as Uniform weight, Blackman-Harris, Tylor, and Dolph-Chebyshev were used to control the side lobe level of the arrays.

This paper also shows how to implement null steering procedure to circumvent the jamming and high interference angles.

Only the linear and two dimensional arrays were taken into consideration.
