Design of Integrated Waveform for Detection and Cover Based on Maximum Value Constraint

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper proposes a method for designing integrated waveform with excellent autocorrelation and interference properties. The generated waveform not only achieves a low peak sidelobe level but also introduces controllable false targets to deceive non‐cooperative radars.

Main lobe deceptive jamming suppression based on blind source separation and energy detection for monopulse radar

IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2170-2181, November 2024.
The authors proposed a main lobe deceptive jamming suppression method for monopulse radar based on BSS and energy detection, which can achieve interference suppression while accurately estimating the angle of the real target. Abstract Main lobe deceptive jamming always causes the serious degradation of signal detection ability and angle measurement ...

Deep Learning‐Based Active Jamming Suppression for Radar Main Lobe

IET Signal Processing, Volume 2024, Issue 1, 2024.
Due to the development of digital radio frequency memory (DRFM), active jamming against the main lobe of the radar has become mainstream in electronic warfare. The jamming infiltrates the radar receiver via the main lobe, covering up the target echo information. This greatly affects the detection, tracking, and localization of targets by radar. In this

Interrupted Sampling Repeater Jamming Recognition Method Based on Wavelet Packet Transform

IEEE Access
The radar jammers operating in an interrupted sampling repeater jamming (ISRJ) mode can intercept transmitted signal, modulate the intercepted signal slices, and retransmit them back to the radar receiver to create coherent interference.
