HELLO EVERYONE

hope everyone is fine.need some help guys

anyone who has worked on TDOA. i have made the algorithm but i am implementing it on hardware now.can anybody plzzz help me

best regards

What is the difference between this question and your previous https://www.mathworks.com/matlabcentral/answers/609791-tdoa-and-correlation-in-matlab?s_tid=srchtitle ?

thankyou so much sir for your kind reply

actually your help is quiet appreciated. actually i am still having some questions

Hello,

I have a slightly different problem.

When I use something for x_s y_s z_s, then that's my result in the plot. How can that be?

In my case I have 4 receivers and I know the time differences between them. I want to find the sound source.

Do I get the code wrong or how can I run it?

Thanks

Best Regards

i did'nt get your question. please be a bit brief.

even you have 4 receivers, the code is same. there should not be any problem.

I know the time differences and want to find the source.

How do I have to use the code?

Answer 1

[Walter Roberson]

sir i want that my result should be displayed as

Change

possibleSol(1,1)
possibleSol(2,1)
possibleSol(3,1)

to

fprintf('Xs=%g\n', possibleSol(1,1));
fprintf('Ys=%g\n', possibleSol(2,1));
fprintf('Zs=%g\n', possibleSol(3,1));

and then i want to plot my receivers coordinates which is the array of x,y and z as circle

scatter3(x, y, z, 'o');
hold on

and the Xs,Ys and Zs as cross on a single 3D graph

scatter3(possibleSol(1,1), possibleSol(2,1), possibleSol(3,1), '+');
hold off
legend({'Receivers', 'Source'})

HATS OFF sir!!!

Where can I find a Matlab TDOA algorithm where I can just input my sensor positions and the time delays?!
