Comparison of scattered signal waveform recovery techniques under low SNR for target identification
(2017 11th European Conference on Antennas and Propagation, EUCAP 2017, 2017)
Target identification from scattered electromagnetic waves is a difficult problem especially at low SNR levels, which prevents extraction of distinguishable information. When a scattered signal is corrupted by noise, it ...
The effects of geometric scattered signal waveform modeling on target identification performance
(2017 11th European Conference on Antennas and Propagation, EUCAP 2017, 2017)
Target identification from scattered signals using time domain techniques depend significantly on the waveform. Recently, a novel feature set is proposed which encounter structural properties of the waveform and collects ...
Hierarchical Reconstruction and Structural Waveform Analysis for Target Classification
(IEEE Transactions on Antennas and Propagation, 2016)
Classification of objects from scattered electromagnetic waves is a difficult problem, as it heavily depends on aspect angle. To minimize this dependency, distinguishable features can be used. In this paper, we propose a ...
Application of dielectric resonator based metamaterial in waveguide coupler
