MATLAB: Move phased.conformalArray phase reference center

phase reference center of arrayPhased Array System Toolbox

Once I use phased.conformalArray to create an array 1. where is the array phase reference center? 2. how to move the array phase reference center to any place I want, assuming plane waves incoming?

For a conformal array, you define the position of each element in an [x;y;z] format, then there is an implicit origin for these coordinates. If you want to move it, the best way in my opinion is to adjust the coordinates according to the new origin.

MATLAB: Is it possible to create an L-shaped phased array using the Phased Array Toolbox

Yes you can use Phased Array System Toolbox to do this, here is a small example to show that

d = 0.5;
N = 4;
pos_along_x = (0:N-1)*d;
pos_along_y = (1:N-1)*d;
pos_along_z = (1:N-1)*d;
pos = [[pos_along_x zeros(1,2*(N-1))];...
   [zeros(1,N) pos_along_y zeros(1,N-1)];...
   [zeros(1,2*N-1) pos_along_z]];
my_array = phased.ConformalArray('ElementPosition',pos);
viewArray(my_array);

MATLAB: Rotate elements in phase.ConformalArray

Phased Array System Toolbox currently does not have a parameter for this. Thanks for the question and I'll take note for the request. At this point, the best way to do this may be to create a heterogeneous array, like phased.HeterogeneousConformalArray, and then assign the slightly rotated pattern to each element.
