Compressed Sensing Radar Imaging: Fundamentals, Challenges, and Advances. [PDF]

open access: yesSensors (Basel), 2019
In recent years, sparsity-driven regularization and compressed sensing (CS)-based radar imaging methods have attracted significant attention. This paper provides an introduction to the fundamental concepts of this area. In addition, we will describe both

Array Radar Three-Dimensional Forward-Looking Imaging Algorithm Based on Two-Dimensional Super-Resolution [PDF]

open access: yesSensors
Radar imaging is a technology that uses radar systems to generate target images. It transmits radio waves, receives the signal reflected back by the target, and realizes imaging by analyzing the target’s position, shape, and motion information. The three-

MIMO-SAR: A Hierarchical High-Resolution Imaging Algorithm for mmWave FMCW Radar in Autonomous Driving [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2021
Millimeter-wave radars are being increasingly integrated into commercial vehicles to support advanced driver-assistance system features. A key shortcoming for present-day vehicular radar imaging is poor azimuth resolution (for side-looking operation) due

Parameter Estimation for Interrupted Sampling Repeater Jamming Based on ADMM

open access: yesSensors, 2021
By repeatedly sampling, storing, and retransmitting parts of the radar signal, interrupted sampling repeater jamming (ISRJ) based on digital radio frequency memory (DRFM) can produce a train of secondary false targets symmetrical to the main false target,

Radar Imaging with EISCAT 3D [PDF]

open access: yesAnnales Geophysicae, 2020
Abstract. A new incoherent scatter radar called EISCAT 3D is being constructed in Northern Scandinavia. It will have the capability of producing volumetric images of ionospheric plasma parameters using aperture synthesis radar imaging. This study uses the current design of EISCAT 3D to explore the theoretical radar imaging performance and compares ...

Reconfigurable integrated structures with functions of Fabry–Perot antenna and wideband liquid absorber for radar system stealth

open access: yesScientific Reports, 2023
This paper proposes a functionally reconfigurable integrated structure of a Fabry–Perot (FP) antenna and wideband liquid absorber. First, a two-layer partial reflecting surface (PRS) has been designed.

Microwave Photonic Imaging Radar With a Sub-Centimeter-Level Resolution [PDF]

open access: yesJournal of Lightwave Technology, 2020
Microwave photonic radars enable fast or even real-time high-resolution imaging thanks to its broad bandwidth. Nevertheless, the frequency range of the radars usually overlaps with other existed radio-frequency (RF) applications, and only a centimeter ...

Frequency-Scaling-Based Spaceborne Squint SAR Sparse Imaging

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
In synthetic aperture radar (SAR), due to the characteristics of squint data in spaceborne imaging geometry, a more accurate range cell migration correction operation is necessary.
