MATLAB: Phased Array System Toolbox

Phased Array System Toolboxsound localization

Hello,

I am using DOA algorithm to localize high frequency sources with microphone arrays. The Default DOA code has used ULA and URA Arrays but I am trying to use conformal Arrays. I want to know that why we have to divide element positions by Lambda when difining 'pos'. pos = getElementPosition(h)/lambda;

Regards Ali

Could you elaborate a bit more what functions you are using? Phased Array System Toolbox has a set of functions that works only with narrowband signals. These functions take element positions and because they work on a single frequency, the element positions are expressed in wavelength.

MATLAB: Target angle set up in a radar simulation without phase shifter

You should use tgtang. Note that what you do here is to synthesize the data. Therefore, even though the radar is not steering, you need to know what is the corresponding directional response of the radar toward the target. Therefore you need to use the direction toward the target.

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);
