FMCW Radar for Noncontact Bridge Structure Displacement Estimation

IEEE Transactions on Instrumentation and Measurement, 2023
The displacement on the bridge structure is an essential parameter in identifying the bridge structure’s health. The noncontact measurement method is preferable in practice, and the radar system is potentially employed for developing displacement ...

FMCW Implementation on LabVIEW

2018 International Conference on Computer and Applications (ICCA), 2018
Thereare many possible system implementations for the Frequency Modulated Continuous Wave (FMCW) radar. In this paper, we will perform a full system level analysis for the implementation of the FMCW using LabVIEW communication. In the FMCW systems, the frequency is modulated at the source in order to measure the distance of the target and the velocity ...

Impact of Phase Noise on FMCW and PMCW Radars

International Radar Conference, 2023
Phase noise can severely degrade the radar performances by producing strong sidelobes which may mask small targets. Reducing those sidelobes by improving the radar analog front-end severely increases the system complexity.

Target Indication With FMCW-OAM Radar

IEEE Geoscience and Remote Sensing Letters, 2023
Vortex electromagnetic (EM) waves, which carry orbital angular momentum (OAM), can provide more information of the target in radar imaging and target detection. Pulsed radar is often used in current OAM radar design.
