Ship HRRP target recognition against decoy jamming based on CNN‐BiLSTM‐SE model
IET Radar, Sonar & NavigationDue to the thinner resolution range of broadband radar, ship recognition issues arise such that minor fluctuations within the targeted area significantly affect the high‐resolution range profile (HRRP) of ships.

Flexible blanket synthetic aperture radar jamming using joint frequency and phase modulation
IET Radar, Sonar &Navigation, Volume 17, Issue 7, Page 1129-1141, July 2023., 2023 In this study, a flexible blanket jamming method against SAR is proposed using joint frequency and phase modulation. The proposed method can form two‐dimensional square‐shaped blanket sidelobes in the SAR image by the coded phase modulation in both fast and slow time domain.

IET Radar, Sonar &Navigation, Volume 17, Issue 3, Page 503-521, March 2023., 2023 A new 3D reconstruction method for stable targets from sequential ISAR images is proposed in this paper. Firstly, the inverse synthetic aperture radar (ISAR) images are preprocessed with the CLEAN algorithm. The maximum between‐cluster variance method (OTSU) is applied to extract feature points from the processed images.

IET Radar, Sonar &Navigation, Volume 17, Issue 2, Page 153-178, February 2023., 2023 Abstract A multi‐function radar is designed to perform disparate functions, such as surveillance, tracking, fire control, amongst others, within a limited resource (time, frequency, and energy) budget. A radar resource management (RRM) module within a radar system makes decisions on prioritisation, parameter selection, and scheduling of associated ...
