NONLINEAR SUBPROFILE SPACE FOR RADAR HRRP RECOGNITION

Progress In Electromagnetics Research Letters, 2012
In this paper, a novel approach, namely nonlinear subprofile space (NSS), is proposed for radar target recognition using high-resolution range profile (HRRP). First, the HRRP samples are mapped into a high-dimensional feature space using nonlinear mapping.
