“…In order to analyse the relationship between the polarisation parameter and the P‐STAP performance, some typical polarisation parameters are given below. - (1) The polarisation degree can denote the clutter distribution on principal eigenvector and secondary eigenvector, which is given as [9]
- (2) The polarisation distance can denote the polarisation difference on Poincare sphere, which is given as ρ d [11]
