Fig. 2From: Measurement and evaluation method of radar anti-jamming effectiveness based on principal component analysis and machine learningPrincipal component analysis scatter plot; The six radar performance indicators are divided into two groups. The first principal component is positively correlated with \(y_1\) and \(y_3\), while negatively correlated with \(y_2\) and \(y_4\). And the second principal component is positively correlated with \(y_5\) and \(y_6\)Back to article page
