2009 International Waveform Diversity and Design Conference, 2009 Multiple-input multiple-output (MIMO) extensions to radar systems enable a number of advantages compared to traditional approaches. These advantages include improved angle estimation and target detection. In this paper, MIMO ground moving target indication (GMTI) radar is addressed. The concept of coherent MIMO radar is introduced.

GMTI radar minimum detectable velocity. [PDF]
, 2011 Minimum detectable velocity (MDV) is a fundamental consideration for the design, implementation, and exploitation of ground moving-target indication (GMTI) radar imaging modes. All single-phase-center air-to-ground radars are characterized by an MDV, or a minimum radial velocity below which motion of a discrete nonstationary target is indistinguishable

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

Electronics 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

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

Journal 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 ...
