Ground moving target indication of polarimetric interferometric synthetic aperture radar using joint scattering vector

open access: yesIET Radar, Sonar & Navigation
Ground moving target indication (GMTI) plays a critical role in both civilian applications and military applications. The accuracy of complex images coregistration is a major factor for multichannel synthetic aperture radar (SAR) GMTI.

A radar extended target angle estimation method based on effective phase clustering

open access: yesThe Journal of Engineering, Volume 2023, Issue 12, December 2023., 2023
Multiple scatter points detected from extended targets in high‐resolution radar systems are often difficult to match with real target points due to uncertain factors such as clutter and system noise. To address this issue, this paper introduces the concept of effective phase and proposes a direction of arrival (DOA) angle estimation method for extended

Moving target detection method based on CUR‐RPCA for missing array elements

open access: yesIET Radar, Sonar &Navigation, Volume 16, Issue 12, Page 2089-2103, December 2022., 2022
Abstract Moving target detection performance is seriously affected by missing array elements for multichannel synthetic aperture radar (Multi‐SAR) systems. Meanwhile, there is a contradiction between the accuracy of data recovery and the computational burden in traditional methods.

An enhanced particle filtering method for GMTI radar tracking [PDF]

open access: yes, 2016
This paper investigates the problem of ground vehicle tracking with a Ground Moving Target Indicator (GMTI) radar. In practice, the movement of ground vehicles may involve several different manoeuvring types (acceleration, deceleration, standstill, etc.).

A SAR‐GMTI method based on changes of polarization characteristics before and after clutter suppression

open access: yesElectronics Letters, Volume 58, Issue 8, Page 324-326, April 2022., 2022
Abstract Due to the azimuth shift and defocus of the moving targets in the synthetic aperture radar image domain, a new synthetic aperture radar ground moving target indication method is proposed in this letter based on the changes of moving targets’ polarization characteristics before and after clutter suppression. This method can effectively suppress

Multisensor Management Method for Ground Moving Target Tracking Based on Doppler Blind Zone Information

open access: yesJournal of Sensors, Volume 2022, Issue 1, 2022., 2022
Tracking ground moving target with sensors proves to be a challenge due to the uncertainty of target motion area, the existence of Doppler blind zone (DBZ), and the complex terrain. In this paper, a multisensor management method based on DBZ information is presented, in which the available sensors are selected to obtain the best operational revenues ...

Multi-aspect SAR-GMTI and Experimental Research on Gaofen-3 SAR Modes

open access: yesLeida xuebao, 2020
Multi-aspect SAR is a new SAR mode that has two advantages, i.e., long-term observations and a large synthetic-aperture azimuth angle. Previous studies have reported that these unique advantages enable even single-channel systems to have a relatively ...
