IET Communications, Volume 20, Issue 1, January/December 2026.This paper introduces a novel AMR method named IUDR‐Net to address the challenge of poor recognition accuracy under low SNR conditions. The method first employs the improved U‐Lite network to suppress the impact of noise effectively and then adopts the ResNet18‐1D network to perform the AMR task efficiently.

Sig2text: A Vision‐Language Model for Non‐Cooperative Radar Signal Parsing
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.We propose Sig2text, a symbolic radar signal recognition and parameter estimation framework that treats waveform analysis as a parsing task using a vision‐language model. By integrating time‐frequency representations with a context‐free grammar and transformer‐based architectures, Sig2text accurately identifies complex modulation types and estimates ...

WFH: A Wideband Frequency Hopping‐Based Anti‐Jamming Navigation Signal Structure
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Given the limitations of existing satellite navigation signals in antijamming performance amid growing environmental jamming, this paper proposes a navigation signal structure based on wideband frequency hopping (WFH) modulation to enhance both antijamming capability and measurement accuracy. It further introduces the nonstationary effective carrier‐to‐

Detection of Unknown Radar Pulses Using Spiking Neural Networks
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This article proposes to use spiking neural networks (SNNs) to detect multiple pulses in observation windows from a superheterodyne receiver. The method is described from encoding to postprocessing. New metrics are introduced to compare the proposed detection method to the energy detector (ED), to a detection based on difference Of boxes (DOB) filters ...
