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.

EURASIP Journal on Advances in Signal Processing, 2021 The interrupted transmitting and receiving (ITR) can be used in anechoic chamber to solve the coupling between the transmitted and reflected signals. When the ITR periods are random, the fake peaks in high-resolution range profile (HRRP) of ITR echo can ...

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 ...

Scientific Programming, Volume 2023, Issue 1, 2023., 2023 A synthetic aperture radar (SAR) automatic target recognition (ATR) method is developed based on the two‐dimensional variational mode decomposition (2D‐VMD). 2D‐VMD decomposes original SAR images into multiscale components, which depict the time‐frequency properties of the targets.
