Low SNR FMCW signal processing with prior information

工程科学学报, 2015
A solid surface frequency modulated continuous wave (FMCW) radar signal model was built to solve the range ambiguity problem of wideband and low signal-to-noise ratio (SNR) FMCW signal under severe measurement conditions.

Variational Signal Separation for Automotive Radar Interference Mitigation [PDF]

arXiv
Algorithms for mutual interference mitigation and object parameter estimation are a key enabler for automotive applications of frequency-modulated continuous wave (FMCW) radar. In this paper, we introduce a signal separation method to detect and estimate radar object parameters while jointly estimating and successively canceling the interference signal.

Passive Radar at the Roadside Unit to Configure Millimeter Wave Vehicle-to-Infrastructure Links [PDF]

arXiv, 2019
Millimeter wave (mmWave) vehicular channels are highly dynamic, and the communication link needs to be reconfigured frequently. In this work, we propose to use a passive radar receiver at the roadside unit to reduce the training overhead of establishing an mmWave communication link.

An Extended Polar Format Algorithm for Joint Envelope and Phase Error Correction in Widefield Staring SAR with Maneuvering Trajectory

Remote Sensing
Polar format algorithm (PFA) is a widely used high-resolution SAR imaging algorithm that can be implemented in advanced widefield staring synthetic aperture radar (WFS-SAR). However, existing algorithms have limited analysis in wavefront curvature error (

Three dimensional scattering center imaging techniques [PDF]

Two methods to image scattering centers in 3-D are presented. The first method uses 2-D images generated from Inverse Synthetic Aperture Radar (ISAR) measurements taken by two vertically offset antennas.
