% Detection probabilityPd = linspace(0.01,0.995,100);
% Probability of false alarmPfa = [1e-8 1e-4];
% Number of received pulsesn = [1 10 50];
% Fluctuation loss for Swerling 1 caseL1f = zeros(numel(Pd),numel(Pfa),numel(n));
% Fluctuation loss for Swerling 2 caseL2f = zeros(numel(Pd),numel(Pfa),numel(n));
for i = 1:numel(n)    % Detectability factor for a steady target    D0n = detectability(Pd,Pfa,n(i),'Swerling0');
    % Detectability factor for Swerling 1 case fluctuating target    D1n = detectability(Pd,Pfa,n(i),'Swerling1');
    % Detectability factor for Swerling 2 case fluctuating target    D2n = detectability(Pd,Pfa,n(i),'Swerling2');
    L1f(:,:,i) = D1n-D0n;    L2f(:,:,i) = D2n-D0n;end
figureax1 = subplot(1,2,1);helperPlotFluctuationLoss(ax1,Pd,L1f)
title(ax1,{'Fluctuation Loss','Swerling 1 Case'});labels = helperLegendLabels('N=%d','P_{fa}=%.0e',n,Pfa);legend(labels)
ax2 = subplot(1,2,2);helperPlotFluctuationLoss(ax2,Pd,L2f)
title(ax2,{'Fluctuation Loss','Swerling 2 Case'})legend(labels)
