A New MCMC Sampling Based Segment Model for Radar Target Recognition [PDF]

open access: yes, 2015
One of the main tools in radar target recognition is high resolution range profile (HRRP)‎. ‎However‎, ‎it is very sensitive to the aspect angle‎. ‎One solution to this problem is to assume the consecutive samples of HRRP identically independently ...

An Approach to Automatic Target Recognition in Radar Images Using SVM [PDF]

open access: yes, 2006
This paper introduces an Automatic Target Recognition (ATR) method based on X Band Radar image processing. A software which implements this method was developed following four principal stages: digital image formation, image preprocessing, feature selection through a combination of C4.5 Decision Tree and PCA and classification using SVM.
