Performance Analysis of New Variable Loading based Robust Rectangular Antenna Array Beamformer

This paper describes the performance of robust rectangular antenna array beamformer using new variable loading technique against steering vector error. Steering vector error is an important factor for practical implementation of the beamformer and the outcome of the paper shows that the robust beamformer performs well at erroneous and error free condition. Rectangular array is essential for the modern space limited situation where the array can scan around 360 degrees and required less space for array elements positioning. The result of the technique is compared with other published loading technique applied to rectangular array.
