Dolph-Chebyschev for a 2D array

[Alberich]

Hi all,
I am serching for some matlab codes simulating a dolph Chebychev array,

and also I want to know , if it is possible to apply this method for 2 d array (rectangular).

Thanks in advance
and best regards

I don't know Matlab Code for this, anyway rememebre that ther are not "easy" foruma for large dolph-chebyschev array (for small linear array a closed form is avilable but it becomes quckly unstable !!!).

Concerning the 2D array the answer is yes ! it is possible using particular transformation obtain a pencil beam sorrounded by "quasi circular" side lobe topography by means of 2D rectangular lattice.
