A Sparse Uniform Linear Array DOA Estimation Algorithm for FMCW Radar
IEEE Signal Processing Letters, 2023Sparse arrays offer evident advantages over their uniform linear counterparts, including larger aperture and higher angular resolution. Despite their benefits, typical sparse arrays, such as nested and coprime arrays, exhibit increased complexity, and ...

IEEE Transactions on Antennas and Propagation, 2023
A novel compact multiple-input multiple-output (MIMO) antenna is proposed with wideband gain enhancement. It consists of two identical antenna elements spacing about half wavelength. First, a 1-to-2 Y-shaped power divider with wideband anti-phase outputs

A Coherent CZT-Based Algorithm for High-Accuracy Ranging With FMCW Radar
IEEE Transactions on Instrumentation and Measurement, 2023The essence of frequency-modulated continuous wave (FMCW) radar-ranging is to estimate the frequency of the beat signal, and the frequency’s accuracy determines the range accuracy.

FMCW Radar for Noncontact Bridge Structure Displacement Estimation
IEEE Transactions on Instrumentation and Measurement, 2023The 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 ...

Polarimetric FMCW weather radar
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015This study which was conducted as a Master's thesis, is a radar system working at X band. In this system, a 2 Watt continuous electromagnetic wave which is modulated with frequency ramp of 30 MHz bandwidth is generated and radiated through TX antenna. The scattered signal from the hydrometeors is multiplied with the transmitted one and beat signal is ...
