%% Animate Existing Polar Azimuth Plot Data % Create a 15-element ULA of cosine antennas with elements spaced one-half % wavelength apart. Plot the directivity of the array at 20 GHz. %% % *Note:* This example runs only in R2016b or later. If you are using an earlier % release, replace each call to the function with the equivalent |step| % syntax. For example, replace |myObject(x)| with |step(myObject,x)|. fc = 20.0e9; c = physconst('Lightspeed'); lam = c/fc; angs = [-180:1:180]; antenna = phased.CosineAntennaElement('FrequencyRange',[1.0e9,100.0e9],... 'CosinePower',[2.5 2.5]); array = phased.ULA('Element',antenna,'NumElements',15,'ElementSpacing',lam/2); a = pattern(array,fc,angs,0); P = polarpattern(angs,a); %% % Then, steer the array to 45° and, using the |animate| method, replace % the existing polar plot with the steered array directivity. steervec = phased.SteeringVector('SensorArray',array,'PropagationSpeed',c,... 'IncludeElementResponse',true); sv = steervec(fc,[45;0]); a1 = pattern(array,fc,angs,0,'Weights',sv); animate(P,angs,a1);
