Analysis of the influence of ESM direction finding error on positioning error

One 、Matlab Code

clc;clear;close all
%%  Analysis of positioning error caused by angle error 

%%  Input parameters 
% AngleError=2;% DF error , The unit of 
DistRadial=50:10:700;% Radial distance , Company Km

%%  Error calculation 
AngleError=[0.2 0.5 1 1.5 2 3 5 8 10 12 15];
AngleError=AngleError';
for i=1:length(AngleError)
    DistError=tand(AngleError(i))*DistRadial;
    plot(DistRadial,DistError);
    hold on
end

xlabel(' Radial distance /Km');
ylabel(' Positioning error /Km');
grid on
legend(num2str(AngleError));
