Ship HRRP target recognition against decoy jamming based on CNN‐BiLSTM‐SE model

open access: yesIET Radar, Sonar & Navigation
Due 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.

Similarity‐oriented method for inverse synthetic aperture radar imaging with low signal‐to‐noise ratio

open access: yesIET Radar, Sonar & Navigation
Noise impairs the performance of inverse synthetic aperture radar (ISAR) motion compensation, which induces severe defocusing under low signal‐to‐noise ratio environments.

Flexible blanket synthetic aperture radar jamming using joint frequency and phase modulation

open access: yesIET 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.

Three‐dimensional point cloud reconstruction of inverse synthetic aperture radar image sequences based on back projection and iterative closest point fusion

open access: yesIET 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.

Artificial intelligence meets radar resource management: A comprehensive background and literature review

open access: yesIET 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 ...

Sparse processing with range migration compensation capability for a frequency agile orthogonal frequency division multiplexing waveform

open access: yesIET Radar, Sonar & Navigation, 2022
Digital‐to‐analogue and analogue‐to‐digital in a digital array radar limits the transmission and reception of instantaneous broadband signals (IBSs), which makes it a technical bottleneck for digital array radar to obtain an instantaneous broadband high ...
