Radar and Visualization of objects

Whats the best way to visualize tracked objects via radar? Does a toolbox exist for that purpose?

What does your signal look like? Are you interested in visualizing a matched filter output? A range estimate?

I would like to start with a single point in a cartesian coordinate which refreshes every 0.01s.

I want to hold my plot, plot the new point and delete my old. So i can visualize a tracked object and see it moving in a coordinate system.

I started with this code:

    % Code
function realtime_plot(x_pos, y_pos)
hLine = plot(nan,nan,'r*');                     
axis([0 10 0 10])                           
grid on;
while(1)  
  set(hLine, 'YData', x_pos, 'XData', y_pos);   
  drawnow                                      
end

It works in matlab but not when i try to use it as a function block in simulink. If i do that, nothing happens.

Ok i solved the problem. The mistake was the while loop. Dont need it for simulink.
