Time-domain and frequency-domain feature selection for reliable radar target identification

The authors discuss the development of useful techniques for selecting features from radar backscatter measurements. This investigation is primarily motivated by interest in the design of radar target identification (RTI) systems that utilize frequency-diverse and polarization-diverse measurements of radar backscatter. Techniques for selecting sets of features from time-domain data and frequency-domain data are presented. The performance of radar target identification systems employing the resulting sets of features is evaluated by means of Monte-Carlo simulation studies.<
