Abstract EN
In practice, random errors in the excitations (amplitude and phase) of array elements cause undesired variations in the array patterns.
In this paper, the clustered array elements with tapered amplitude excitations technique are introduced to reduce the impact of random weight errors and recover the desired patterns.
The most beneficial feature of the suggested method is that it can be used in the design stage to count for any amplitude errors instantly.
The cost function of the optimizer used is restricted to avoid any unwanted rises in sidelobe levels caused by unexpected perturbation errors.
Furthermore, errors on element amplitude excitations are assumed to occur either randomly or sectionally (i.
e.
, an error affecting only a subset of the array elements) through the entire array aperture.
The validity of the proposed approach is entirely supported by simulation of array elements cause undesired variations in the array patterns.
