The T-Mixture Model Approach for Radar HRRP Target Recognition
Caiyun Wang, Jiling Xie · International Journal of Computer and Electrical Engineering · 2013
This paper addresses the problem of automatic radar target recognition using high-resolution range profile (HRRP).We develop a t-mixture model (TMM) to model radar echoes from each target as the t-distribution forms.Estimation of the model parameters is achieved using a modified expectation-maximization (EM), i.e., fuzzy EM (FEM) algorithm.Numerical simulation results show that the proposed approach can achieve good performance of robustness and higher recognition rate.It is helpful for real-time identification and the engineering implements of automatic target recognition using HRRP.
