The output from importdata function seems to be struct.
Theta (B1:B360) looks like only 90[deg] or 270[deg].
Date= importdata('radd.csv')
Date = struct with fields:
data: [360×7 double] textdata: {360×1 cell} rowheaders: {360×1 cell}
dB = Date.data(1:360,3);
% pol_1 = 10*log10(Data(1:121,3)./max(Data(1:121,3)));
Theta = Date.data(1:360,1)*pi/180;
dB = dB-min(dB);
polarplot (Theta,(dB/50))
