    Comparison of Scattered Signal Waveform Recovery Techniques Under Low SNR for Target Identification
    (IEEE, 2017) M. Alper Selver; Mustafa Secmen; E. Yesim Zoral; Selver, M. Alper; Zoral, E. Yesim; Secmen, Mustafa
    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 should be recovered before further processing such as feature extraction and classification. This recovery can be performed in time domain frequency domain or via time-frequency analysis. In this study three important techniques are used for distortion correction and their performances are compared. The analyses are performed with both simulated and measured data from various conducting and dielectric targets having different size geometry and material type.

    The Effects of Geometric Scattered Signal Waveform Modeling on Target Identification Performance
    (IEEE, 2017) M. Alper Selver; Mustafa Secmen; E. Yesim Zoral
    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 local extrema points to model the scattered signal via triangularization. Then using this piecewise model it extracts several morphological features and employs them for target identification through classification. This study expands that approach by modeling the scattered signal with other geometric shapes and accordingly by enriching the feature set. Such an approach requires careful representation of the waveform model since more than one morphology is considered to represent sub-waves of the waveform. The effects of the proposed approach are observed by applications on spherical targets having different size and material type.
