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‐

A Design Concept of CNN Counter to Noise Interference in Radar Signals Classification

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This article explains the relationship between the noise energy and the size of output feature maps, and advance the concept of compression and dilation of CNN architecture which depends on the balance of noise energy and the number of features. ABSTRACT Radar signals classification plays an increasingly significant role in electronic reconnaissance ...

Processing and Resolution Losses Due to Range Cell Migration—Application to Automotive Radar

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This study analyzes how range cell migration (RCM) affects pulse compression and Doppler processing in high‐resolution radar systems. Theoretical models including RCM effects are developed for both pulse and frequency‐modulated continuous wave (FMCW) radar. Resolution and processing losses are quantified for FMCW, linearly frequency‐modulated (LFM) and

Improved Vital Signal Detection Method Based on Multi‐Regions of Interest Joint Enhancement for 4D Through‐Wall Imaging Radar

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Aiming at the problem of a low signal‐to‐noise ratio (SNR) and micro‐motion interference of vital signal behind obstacles, this paper proposes a vital signal detection method based on multiple regions of interest (multi‐ROI) joint enhancement for 4D TWIR.
