The simple analysis method of nonlinear frequency distortions in FMCW radar
Journal of Telecommunications and Information Technology, 2001 The paper presents a simple method for estimating nonlinear frequency distortions of linear frequency modulated (LFM) signals used in FMCW radars. This method, derived from the polynomial model of the nonlinear FM signal phase, is based on finding the ...

Stereoscopic 3D geometric distortions analyzed from the viewer's point of view.
PLoS ONE, 2020 Stereoscopic 3D (S3D) geometric distortions can be introduced by mismatches among image capture, display, and viewing configurations. In previous work of S3D geometric models, geometric distortions have been analyzed from a third-person perspective based

Effect of frequency and flexibility ratio on the seismic response of deep tunnels
Underground Space, 2017 Two-dimensional dynamic numerical analyses have been conducted, using FLAC 7.0, to evaluate the seismic response of underground structures located far from the seismic source, placed in either linear-elastic or nonlinear elastoplastic ground.

Target metric and Shell Shaping
Curved and Layered Structures, 2021 We exploit the possibility of deforming a shell by assigning a target metric, which, for 2D structures, is decomposed into the first and second target fundamental-forms.

Physics and Imaging in Radiation Oncology, 2020 Magnetic resonance imaging (MRI) has exquisite soft-tissue contrast and is the foundation for image guided radiotherapy (IGRT) with integrated magnetic resonance linacs. However, MRI suffers from geometrical distortions. In this study the MRI system- and

Analytical Analysis of SER for Beyond 5G Post-OFDM Waveforms in Presence of High Power Amplifiers
IEEE Access, 2019 This paper studies the performance of enhanced multicarrier waveforms in the presence of a nonlinear memoryless high power amplifier (HPA). In particular, we focus on the in-band non-linear distortions (NLD) and their effects on symbol-error-rate. First,

Hardware Design of a High Dynamic Range Radio Frequency (RF) Harmonic Measurement System
Instruments, 2018 Radio frequency (RF) circuit elements that are traditionally considered to be linear frequently exhibit nonlinear properties that affect the intended operation of many other RF systems. Devices such as RF connectors, antennas, attenuators, resistors, and
