Measured false alarm probability (for \({\hat{\lambda }}^{\mathrm{CFAR-CLT}}\), \({\hat{\lambda }}^{\mathrm{CFAR-F}}\) and \({\hat{\lambda }}^{\mathrm{CFAR-WH}}\)) and measured miss-detection probability (for \({\hat{\lambda }}^{\mathrm{CDR-CLT}}\), \({\hat{\lambda }}^{\mathrm{CDR-F}}\) and \({\hat{\lambda }}^{\mathrm{CDR-S}}\)) as a function of \(\gamma\), using \(\hat{P_{\mathrm{f}}}=0.1\), \(\hat{P_{\mathrm{d}}}=0.9\) and \(\sigma _n = \sqrt{1/2}\)
