Detection of Road Foreign Body Intrusion with Synthetic Aperture Radar

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Foreign body intrusion will cause interruption of road transportation and bring great threat to operation safety. Detection of foreign body intrusion is a key step for efficient recognition, location, and tracking of foreign body intrusion. Current detection approaches of foreign body intrusion are available, but can only detect in a certain range.

A SAR-GMTI Approach Aided by Online Knowledge With an Airborne Multichannel Quad-Pol Radar System

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
In the complicated geographical environment, there will be a seriously deleterious effect to the performance of synthetic aperture radar (SAR)-ground moving target indication (SAR-GMTI) system, because it is difficult to obtain the homogeneous training ...

Along-Track Interferometric SAR Systems for Ground-Moving Target Indication: Achievements, Potentials, and Outlook

open access: yes, 2020
Along-track interferometric (ATI) synthetic aperture radar (SAR) has proven a powerful tool for ground-moving target indication (GMTI). ATI-SAR systems use more than one antenna (at least two), mounted on a moving platform and displaced along the ...

Modelling real‐world effects in near‐field SAR collections for compressive sensing

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper develops previously published work on using compressive sensing techniques to suppress sidelobes in SAR images to develop a higher‐fidelity measurement model. Using Cranfield University's GBSAR System a series, experimental measurements are conducted, and image estimation techniques are applied to this real data.

A Novel Jamming Method Based on Micro‐Doppler Modulation and Electromagnetic Meta‐Materials

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
In this paper, the jamming model based on the uniformly accelerated or decelerated rotating corner reflector and the electromagnetic meta‐materials is systematically discussed. Then, correctness of theoretical analysis is verified by simulations based on the airborne SAR echo data. Compared with the existing research, the jamming model proposed in this

Spaceborne Regional Surveillance Ground Moving Target Indication Based on Squint-TOPSAR

open access: yesLeida xuebao, 2015
For military or civilian activities, it is important to monitor the direction of moving targets in a wide area. Traditional regional monitoring uses the airborne scanning mode (ScanSAR) within the limits of the national airspace.

Efficient knowledge‐aided target relocation algorithm for airborne radar

open access: yesThe Journal of Engineering, Volume 2019, Issue 21, Page 7589-7592, November 2019., 2019
This letter addresses the problem of target relocation in wide‐area ground moving target indication system. The antenna pattern information is exploited as prior knowledge to enhance the performance of airborne radar. Firstly, the ideal target relocation model for moving targets based on the dual‐channel radar system is analysed and the mismatch model ...
