A Radar Multipath Signal Parameter Estimation Method in Closed Environments Using Sparsity With Real‐Imaginary Component Characteristics

open access: yesElectronics Letters, Volume 61, Issue 1, January/December 2025.
This method leverages the spatial sparsity of multipath signals and takes into account the real and imaginary components of the radar echo after the inner product with the overcomplete dictionary. It addresses the issues of inaccurate multipath signal parameter estimation, high algorithm complexity, and weak convergence in the multipath signal ...

Space scanning FMCW-based two-dimensional frequency diverse array radar

open access: yesThe Journal of Engineering, 2019
The frequency-modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is extended to two dimensions (2D). The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased ...

FMCW Interference Waveform Estimation Based on Intentional Local Interference for Automotive Radars [PDF]

open access: yesJournal of Electromagnetic Engineering and Science
We propose a new method to estimate the waveforms of frequency-modulated continuous-wave (FMCW) interferers by intentional interference. The proposed method utilizes the crossing interference of FMCW radar by adaptive waveform configuration.

Milimeterwave FMCW radar design

open access: yes, 2020
In traffic radar system, Frequency Modulated Continuous Wave (FMCW) will be used since these radars are preferred in short distance and high range resolution systems.The system to be constructed is not only a system operating with Doppler principle and detection of speed; on the contrary a functional radar is planned to be produced.

RIS-Enabled Self-Localization With FMCW Radar

open access: yesIEEE Transactions on Vehicular Technology
In the upcoming vehicular networks, reconfigurable intelligent surfaces (RISs) are considered as a key enabler of user self-localization without the intervention of the access points (APs). In this paper, we investigate the feasibility of RIS-enabled self-localization with no APs.
