Radar HRRP automatic target recognition: Algorithms and applications

Radar automatic target recognition (RATR) is an important function for modern radar. Target high resolution range profile (HRRP) contains target structure signatures, such as target size, scatterer distribution, etc., thereby radar HRRP target recognition has received intensive attention from the RATR community. Statistical modeling of target HRRPs is the key stage for HRRP statistical recognition, which including model selection and parameter estimation. In this paper, we introduce the recent progress in HRRP based RATR, including the statistical modelling algorithms of HRRP data, robust recognition algorithms for low signal noise ratio(SNR) case, and some results based on the measured data.
