Phase Noise in FMCW Radar Systems [PDF]

IEEE Transactions on Aerospace and Electronic Systems, 2019
Phase noise is one of the fundamental performance parameters in modern radar, communication, spectroscopic, and metrological systems. In this paper, a phase noise theory has been developed for FMCW radar systems. A new design equation has been derived to specify the maximum bound on the allowable source phase noise level in radar systems. The nonlinear

A review of the FATIMA Yellow Sea field campaign research

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 777, April 2026 Part B.
The FATIMA marine fog project took place over the Sable Island region of eastern Canada (summer 2022) and the Yellow Sea of the Republic of Korea (ROK, summer 2023). Its goals are to improve marine fog monitoring and forecasting. Instrumented multiple research vessels, aircraft, tethered balloon and autonomous systems, ocean observation sites, and ...

Prospects of FMCW-based frequency diverse array radar

The Journal of Engineering, 2019
The linear frequency modulated (LFM) frequency modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is investigated in detail. The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as

Time‐Stretched Interferometric LiDAR with Dispersive Wavenumber‐to‐Time Range Encoding

Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
We present a time‐stretched interferometric LiDAR that directly encodes distance into time‐domain interference signals. Operating at 5 MHz with only millimeter‐level coherence length, the system measures up to 12 m with centimeter precision and resolution, achieving high‐speed 3D imaging and dynamic target detection without FFT processing or long ...

Design Considerations for Integrated Radar Chirp Synthesizers

IEEE Access, 2019
Phase-locked loops (PLLs) effectively generate frequency chirps for frequency-modulated continuous-wave (FMCW) radar and are ideal for integrated circuit implementations.

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Characterizing trade‐wind shallow convection regimes in the open sea with a synergy of ship‐based vertical profiling observations

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.
We use active remote sensing from a ship during the EUREC4$$ {\mathrm{EUREC}}^4 $$A campaign to characterize the environment before, during, and after precipitation in shallow convection. (1) Shallow clouds barely precipitate (only virga). Congestus clouds generate precipitation, occurring less often in the afternoon but with higher cloud fractions. (2)

Computationally Efficient Pruning Before Training Scheme for SNN‐Based Radar Gesture Recognition

Electronics Letters, Volume 62, Issue 1, January/December 2026.
In this work, we propose a Spike Timing‐driven Pruning before Training (ST‐PBT) method for radar‐based human gesture recognition. The proposed ST‐PBT performs a single‐shot pruning at the model initialisation, avoiding the expensive computational cost and compression time incurred in the model pre‐training. Furthermore, the ST‐PBT introduces a gradient‐
