Hi Russell,
I understand that you want to create an animated polar plot for an antenna gain pattern.
To create an animated plot for an antenna, gain pattern with a time variable, you can use the “polarplot” function in MATLAB along with a loop to update the gain and phase values at each time step. Here's an example code snippet to get you started:
% Define time variable
t = linspace(0, 2*pi, 100);
% Initialize figure and axes
figure;
ax = polaraxes;
% Loop over time steps
for i = 1:length(t)
% Compute gain and phase values at current time step
gain = sin(t(i)); % Replace with your own gain function
phase = cos(t(i)); % Replace with your own phase function
% Plot polar pattern
polarplot(ax, [0 phase], [0 gain]);
% Customize plot appearance
ax.ThetaZeroLocation = 'top'; % Set theta zero location
ax.RLim = [0 1]; % Set radial limits
% Pause to control animation speed
pause(0.1);
% Clear current plot
cla(ax);
end
In this example, the gain and phase values are computed based on the current time step “t(i)”. You can replace the “sin(t(i))” and “cos(t(i))” functions with your own functions that parameterize the gain and phase with time.
I hope this helps!
