Radar performance indicators	Principal components
	\(Comp_{1}\)	\(Comp_{2}\)	\(Comp_{3}\)
\(y_1\)	0.486	-0.22	0.745
\(y_2\)	− 0.508
\(y_3\)	0.522
\(y_4\)	− 0.429	− 0.376
\(y_5\)	− 0.129	0.67	0.646
\(y_6\)	− 0.183	0.637	− 0.726
Contribution rate	0.602461	0.2886396	0.0550844
Cumulative contribution rate	0.602461	0.8911006	0.946185

\(Comp_{1}\), \(Comp_{2}\) and \(Comp_{3}\), respectively, denote the first, the second and the third principal component
\(y_1\), \(y_2\), \(y_3\), \(y_4\), \(y_5\) and \(y_6\) denote the six radar performance indicators as in Table 4
